Atomicity violation occurs when the fmc_send_cmd() function is executed simultaneously with the modification of the fmdev->resp_skb value. Consider a scenario where, after passing the validity check within the function, a non-null fmdev->resp_skb variable is assigned a null value. This results in an invalid fmdev->resp_skb variable passing the validity check. As seen in the later part of the function, skb = fmdev->resp_skb; when the invalid fmdev->resp_skb passes the check, a null pointer dereference error may occur at line 478, evt_hdr = (void *)skb->data; To address this issue, it is recommended to include the validity check of fmdev->resp_skb within the locked section of the function. This modification ensures that the value of fmdev->resp_skb does not change during the validation process, thereby maintaining its validity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

[PATCH OLK-6.6 v2] EDAC/igen6: Avoid segmentation fault on module unload
by Ye Bin 02 Jan '25

02 Jan '25

From: Orange Kao <orange(a)aiven.io> stable inclusion from stable-v6.6.64 commit 830cabb61113d92a425dd3038ccedbdfb3c8d079 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEDPH CVE: CVE-2024-56708 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fefaae90398d38a1100ccd73b46ab55ff4610fba ] The segmentation fault happens because: During modprobe: 1. In igen6_probe(), igen6_pvt will be allocated with kzalloc() 2. In igen6_register_mci(), mci->pvt_info will point to &igen6_pvt->imc[mc] During rmmod: 1. In mci_release() in edac_mc.c, it will kfree(mci->pvt_info) 2. In igen6_remove(), it will kfree(igen6_pvt); Fix this issue by setting mci->pvt_info to NULL to avoid the double kfree.

In igen6_probe(), igen6_pvt will be allocated with kzalloc() 2. In igen6_register_mci(), mci->pvt_info will point to &igen6_pvt->imc[mc] During rmmod: 1. In mci_release() in edac_mc.c, it will kfree(mci->pvt_info) 2. In igen6_remove(), it will kfree(igen6_pvt); Fix this issue by setting mci->pvt_info to NULL to avoid the double kfree.

[PATCH openEuler-1.0-LTS] media: wl128x: Fix atomicity violation in fmc_send_cmd()
by dinglongwei 31 Dec '24

From: Qiu-ji Chen <chenqiuji666(a)gmail.com> stable inclusion from stable-v4.19.325 commit d16109c9fdc1b8cea4fe63b42e06e926c3f68990 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEDOW CVE: CVE-2024-56700 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ca59f9956d4519ab18ab2270be47c6b8c6ced091 upstream. Atomicity violation occurs when the fmc_send_cmd() function is executed simultaneously with the modification of the fmdev->resp_skb value. Consider a scenario where, after passing the validity check within the function, a non-null fmdev->resp_skb variable is assigned a null value. This results in an invalid fmdev->resp_skb variable passing the validity check. As seen in the later part of the function, skb = fmdev->resp_skb; when the invalid fmdev->resp_skb passes the check, a null pointer dereference error may occur at line 478, evt_hdr = (void *)skb->data; To address this issue, it is recommended to include the validity check of fmdev->resp_skb within the locked section of the function. This modification ensures that the value of fmdev->resp_skb does not change during the validation process, thereby maintaining its validity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

[PATCH OLK-5.10] i40e: fix race condition by adding filter's intermediate sync state
by Zhang Changzhong 31 Dec '24

31 Dec '24

From: Aleksandr Loktionov <aleksandr.loktionov(a)intel.com> stable inclusion from stable-v6.12-rc7 commit f30490e9695ef7da3d0899c6a0293cc7cd373567 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KRJ CVE: CVE-2024-53088 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Fix a race condition in the i40e driver that leads to MAC/VLAN filters becoming corrupted and leaking. Address the issue that occurs under heavy load when multiple threads are concurrently modifying MAC/VLAN filters by setting mac and port VLAN. 1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan(). 2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac(). 3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption. Reproduction steps: 1. Spawn multiple VFs. 2. Apply a concurrent heavy load by running parallel operations to change MAC addresses on the VFs and change port VLANs on the host. 3. Observe errors in dmesg: "Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX, please set promiscuous on manually for VF XX". Exact code for stable reproduction Intel can't open-source now. The fix involves implementing a new intermediate filter state, I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list. These filters cannot be deleted from the hash list directly but must be removed using the full process.

[PATCH openEuler-1.0-LTS] media: wl128x: Fix atomicity violation in fmc_send_cmd()
by dinglongwei 31 Dec '24

31 Dec '24

From: Qiu-ji Chen <chenqiuji666(a)gmail.com> stable inclusion from stable-v4.19.325 commit d16109c9fdc1b8cea4fe63b42e06e926c3f68990 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEDOW CVE: CVE-2024-56700 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ca59f9956d4519ab18ab2270be47c6b8c6ced091 upstream. Atomicity violation occurs when the fmc_send_cmd() function is executed simultaneously with the modification of the fmdev->resp_skb value. Consider a scenario where, after passing the validity check within the function, a non-null fmdev->resp_skb variable is assigned a null value. This results in an invalid fmdev->resp_skb variable passing the validity check. As seen in the later part of the function, skb = fmdev->resp_skb; when the invalid fmdev->resp_skb passes the check, a null pointer dereference error may occur at line 478, evt_hdr = (void *)skb->data; To address this issue, it is recommended to include the validity check of fmdev->resp_skb within the locked section of the function. This modification ensures that the value of fmdev->resp_skb does not change during the validation process, thereby maintaining its validity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

[PATCH openEuler-1.0-LTS] sched/dynamic_affinity: Calculate cpu capacity in real time when realtime tasks are running on this cpu
by He Yujie 31 Dec '24

31 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEBAG -------------------------------- The task_rq selection of dynamic affinity use cpu capacity to determine select_cpus range. When realtime tasks are running on the cpu all the time, cfs tasks and the thread of softirq is suppressed, and the cpu capacity is not updated in time. As a result, the select_cpus range is always selected for preferred_cpus. then cfs task will never be able to run because realtime tasks has been running. Therefore, if realtime tasks is running during the task_rq selection of dynamic affinity, the cpu capacity should be calculated to solve such a problem.

[PATCH openEuler-22.03-LTS-SP1] bpf: fix OOB devmap writes when deleting elements
by Tengda Wu 31 Dec '24

31 Dec '24

From: Maciej Fijalkowski <maciej.fijalkowski(a)intel.com> stable inclusion from stable-v5.10.231 commit 70f3de869865f9c3da0508a5ea29f6f4c1889057 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAPP CVE: CVE-2024-56615 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ab244dd7cf4c291f82faacdc50b45cc0f55b674d upstream. Jordy reported issue against XSKMAP which also applies to DEVMAP - the index used for accessing map entry, due to being a signed integer, causes the OOB writes. Fix is simple as changing the type from int to u32, however, when compared to XSKMAP case, one more thing needs to be addressed. When map is released from system via dev_map_free(), we iterate through all of the entries and an iterator variable is also an int, which implies OOB accesses. Again, change it to be u32.

With mem_ctrl_idx defined as 32-bits wide the left-shift operation truncates the upper 16 bits of information during the calculation of the SMC argument. The mem_ctrl_idx stack variable must be defined as 64-bits wide to prevent any potential integer overflow, i.e. loss of data from upper 16 bits.

If the tag length is >= U32_MAX - 3 then the "length + 4" addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decode_cb_compound4res() does not have to perform arithmetic on the unsafe length value.

But it is possible to attach a non-sleepable BPF program to a uprobe, and non-sleepable BPF programs are freed via normal RCU (see __bpf_prog_put_noref()).

[PATCH openEuler-1.0-LTS] printk: Skip log flush in NMI context when logbuf_lock is held
by Xiaomeng Zhang 31 Dec '24

31 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB963V CVE: NA -------------------------------- In nmi_trigger_cpumask_backtrace(), printk_safe_flush() is called after sending NMI to flush the logs. When logbuf_lock is already held and the current CPU is in printk-safe context (e.g., NMI context), attempting to acquire the lock again can lead to deadlock. Modify the function to return early when detecting logbuf_lock is held and current CPU is in printk-safe context. This prevents deadlock scenarios where CPU0 holds the lock while other CPUs try to acquire it in NMI context.

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBEMJK CVE: NA -------------------------------- Suppose existing call chain: P() -> A() -> B(), B() don't construct stack frame in which fp and lr are saved for call stack unwinding, then if task1 is interrupted as running at address 'B2' and then preempted by task2, and task2 unwind the call stack of task1, it expect to see P->A->B, but actually P->B, A disappeared! A(): A1: stp fp, lr, ... <-- suppose fp_P and lr_P saved A2: mov fp, sp <-- suppose fp_A saved in 'fp' register A3: bl B <-- call to B() A4: mov ... <-- 'A4' saved in 'lr' register B(): B1: mov ...

[PATCH OLK-6.6] virtiofs: use pages instead of pointer for kernel direct IO

As for now, the maximal read size for kvec iter is only limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, so fuse_direct_io() doesn't split the 10MB buffer. It saves the address and the size of the 10MB-sized buffer in out_args[0] of a fuse request and passes the fuse request to virtio_fs_wake_pending_and_unlock(). 4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() to queue the request. Because virtiofs need DMA-able address, so virtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer for all fuse args, copies these args into the bounce buffer and passed the physical address of the bounce buffer to virtiofsd. The total length of these fuse args for the passed fuse request is about 10MB, so copy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter and it triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)) return NULL; 5) virtio_fs_enqueue_req() will retry the memory allocation in a kworker, but it won't help, because kmalloc() will always return NULL due to the abnormal size and finit_module() will hang forever. A feasible solution is to limit the value of max_read for virtio-fs, so the length passed to kmalloc() will be limited. However it will affect the maximal read size for normal read. And for virtio-fs write initiated from kernel, it has the similar problem but now there is no way to limit fc->max_write in kernel. So instead of limiting both the values of max_read and max_write in kernel, introducing use_pages_for_kvec_io in fuse_conn and setting it as true in virtiofs. When use_pages_for_kvec_io is enabled, fuse will use pages instead of pointer to pass the KVEC_IO data. After switching to pages for KVEC_IO data, these pages will be used for DMA through virtio-fs. If these pages are backed by vmalloc(), {flush|invalidate}_kernel_vmap_range() are necessary to flush or invalidate the cache before the DMA operation. So add two new fields in fuse_args_pages to record the base address of vmalloc area and the condition indicating whether invalidation is needed. Perform the flush in fuse_get_user_pages() for write operations and the invalidation in fuse_release_user_pages() for read operations.

In this case, task work will find ->io_wq being already killed and null'ed, which is a problem if it then tries to forward the request to io_queue_iowq(). Make io_queue_iowq() fail requests in this case. Note that it also checks PF_KTHREAD, because the user can first close a DEFER_TASKRUN ring and shortly after kill the task, in which case ->iowq check would race.

As for now, the maximal read size for kvec iter is only limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, so fuse_direct_io() doesn't split the 10MB buffer. It saves the address and the size of the 10MB-sized buffer in out_args[0] of a fuse request and passes the fuse request to virtio_fs_wake_pending_and_unlock(). 4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() to queue the request. Because virtiofs need DMA-able address, so virtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer for all fuse args, copies these args into the bounce buffer and passed the physical address of the bounce buffer to virtiofsd. The total length of these fuse args for the passed fuse request is about 10MB, so copy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter and it triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)) return NULL; 5) virtio_fs_enqueue_req() will retry the memory allocation in a kworker, but it won't help, because kmalloc() will always return NULL due to the abnormal size and finit_module() will hang forever. A feasible solution is to limit the value of max_read for virtio-fs, so the length passed to kmalloc() will be limited. However it will affect the maximal read size for normal read. And for virtio-fs write initiated from kernel, it has the similar problem but now there is no way to limit fc->max_write in kernel. So instead of limiting both the values of max_read and max_write in kernel, introducing use_pages_for_kvec_io in fuse_conn and setting it as true in virtiofs. When use_pages_for_kvec_io is enabled, fuse will use pages instead of pointer to pass the KVEC_IO data. After switching to pages for KVEC_IO data, these pages will be used for DMA through virtio-fs. If these pages are backed by vmalloc(), {flush|invalidate}_kernel_vmap_range() are necessary to flush or invalidate the cache before the DMA operation. So add two new fields in fuse_args_pages to record the base address of vmalloc area and the condition indicating whether invalidation is needed. Perform the flush in fuse_get_user_pages() for write operations and the invalidation in fuse_release_user_pages() for read operations. It may seem necessary to introduce another field in fuse_conn to indicate that these KVEC_IO pages are used for DMA, However, considering that virtio-fs is currently the only user of use_pages_for_kvec_io, just reuse use_pages_for_kvec_io to indicate that these pages will be used for DMA.

The total length of these fuse args for the passed fuse request is about 10MB, so copy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter and it triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)) return NULL; 5) virtio_fs_enqueue_req() will retry the memory allocation in a kworker, but it won't help, because kmalloc() will always return NULL due to the abnormal size and finit_module() will hang forever. A feasible solution is to limit the value of max_read for virtio-fs, so the length passed to kmalloc() will be limited. However it will affect the maximal read size for normal read. And for virtio-fs write initiated from kernel, it has the similar problem but now there is no way to limit fc->max_write in kernel. So instead of limiting both the values of max_read and max_write in kernel, introducing use_pages_for_kvec_io in fuse_conn and setting it as true in virtiofs. When use_pages_for_kvec_io is enabled, fuse will use pages instead of pointer to pass the KVEC_IO data. After switching to pages for KVEC_IO data, these pages will be used for DMA through virtio-fs. If these pages are backed by vmalloc(), {flush|invalidate}_kernel_vmap_range() are necessary to flush or invalidate the cache before the DMA operation. So add two new fields in fuse_args_pages to record the base address of vmalloc area and the condition indicating whether invalidation is needed. Perform the flush in fuse_get_user_pages() for write operations and the invalidation in fuse_release_user_pages() for read operations. It may seem necessary to introduce another field in fuse_conn to indicate that these KVEC_IO pages are used for DMA, However, considering that virtio-fs is currently the only user of use_pages_for_kvec_io, just reuse use_pages_for_kvec_io to indicate that these pages will be used for DMA.

As for now, the maximal read size for kvec iter is only limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, so fuse_direct_io() doesn't split the 10MB buffer. It saves the address and the size of the 10MB-sized buffer in out_args[0] of a fuse request and passes the fuse request to virtio_fs_wake_pending_and_unlock(). 4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() to queue the request. Because virtiofs need DMA-able address, so virtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer for all fuse args, copies these args into the bounce buffer and passed the physical address of the bounce buffer to virtiofsd. The total length of these fuse args for the passed fuse request is about 10MB, so copy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter and it triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)) return NULL; 5) virtio_fs_enqueue_req() will retry the memory allocation in a kworker, but it won't help, because kmalloc() will always return NULL due to the abnormal size and finit_module() will hang forever. A feasible solution is to limit the value of max_read for virtio-fs, so the length passed to kmalloc() will be limited. However it will affect the maximal read size for normal read. And for virtio-fs write initiated from kernel, it has the similar problem but now there is no way to limit fc->max_write in kernel. So instead of limiting both the values of max_read and max_write in kernel, introducing use_pages_for_kvec_io in fuse_conn and setting it as true in virtiofs. When use_pages_for_kvec_io is enabled, fuse will use pages instead of pointer to pass the KVEC_IO data. After switching to pages for KVEC_IO data, these pages will be used for DMA through virtio-fs. If these pages are backed by vmalloc(), {flush|invalidate}_kernel_vmap_range() are necessary to flush or invalidate the cache before the DMA operation. So add two new fields in fuse_args_pages to record the base address of vmalloc area and the condition indicating whether invalidation is needed. Perform the flush in fuse_get_user_pages() for write operations and the invalidation in fuse_release_user_pages() for read operations. It may seem necessary to introduce another field in fuse_conn to indicate that these KVEC_IO pages are used for DMA, However, considering that virtio-fs is currently the only user of use_pages_for_kvec_io, just reuse use_pages_for_kvec_io to indicate that these pages will be used for DMA.

[PATCH OLK-5.10] arm64: stacktrace: Handle 'lr' in interrupt context

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBEMJK CVE: NA -------------------------------- Suppose existing call chain: P() -> A() -> B(), B() don't construct stack frame in which fp and lr are saved for call stack unwinding, then if task1 is interrupted as running at address 'B2' and then preempted by task2, and task2 unwind the call stack of task1, it expect to see P->A->B, but actually P->B, A disappeared! A(): A1: stp fp, lr, ... <-- suppose fp_P and lr_P saved A2: mov fp, sp <-- suppose fp_A saved in 'fp' register A3: bl B <-- call to B() A4: mov ... <-- 'A4' saved in 'lr' register B(): B1: mov ... B2: mov ... <-- interrupt comes, then run into el1_irq() B3: mov ... <-- 'B3' is saved in 'elr_el1' register el1_irq(): ... <-- save registers then construct stack frame Cm: bl arm64_preempt_schedule_irq <-- Can be preempted here Cn: ...

[PATCH openEuler-1.0-LTS] printk: Skip log flush in NMI context when logbuf_lock is held
by Xiaomeng Zhang 30 Dec '24

30 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB963V CVE: NA -------------------------------- In nmi_trigger_cpumask_backtrace(), printk_safe_flush() is called after sending NMI to flush the logs. When logbuf_lock is already held and the current CPU is in printk-safe context (e.g., NMI context), attempting to acquire the lock again can lead to deadlock. Modify the function to return early when detecting logbuf_lock is held and current CPU is in printk-safe context. This prevents deadlock scenarios where CPU0 holds the lock while other CPUs try to acquire it in NMI context.

In this case, task work will find ->io_wq being already killed and null'ed, which is a problem if it then tries to forward the request to io_queue_iowq(). Make io_queue_iowq() fail requests in this case. Note that it also checks PF_KTHREAD, because the user can first close a DEFER_TASKRUN ring and shortly after kill the task, in which case ->iowq check would race.

With mem_ctrl_idx defined as 32-bits wide the left-shift operation truncates the upper 16 bits of information during the calculation of the SMC argument. The mem_ctrl_idx stack variable must be defined as 64-bits wide to prevent any potential integer overflow, i.e. loss of data from upper 16 bits.

[PATCH OLK-5.10] dm cache: fix flushing uninitialized delayed_work on cache_ctr error

From: Ming-Hung Tsai <mtsai(a)redhat.com> stable inclusion from stable-v6.6.61 commit 8cc12dab635333c4ea28e72d7b947be7d0543c2c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5AVP CVE: CVE-2024-50280 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 135496c208ba26fd68cdef10b64ed7a91ac9a7ff upstream. An unexpected WARN_ON from flush_work() may occur when cache creation fails, caused by destroying the uninitialized delayed_work waker in the error path of cache_create(). For example, the warning appears on the superblock checksum error. Reproduce steps: dmsetup create cmeta --table "0 8192 linear /dev/sdc 0" dmsetup create cdata --table "0 65536 linear /dev/sdc 8192" dmsetup create corig --table "0 524288 linear /dev/sdc 262144" dd if=/dev/urandom of=/dev/mapper/cmeta bs=4k count=1 oflag=direct dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \ /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0" Kernel logs: (snip) WARNING: CPU: 0 PID: 84 at kernel/workqueue.c:4178 __flush_work+0x5d4/0x890 Fix by pulling out the cancel_delayed_work_sync() from the constructor's error path. This patch doesn't affect the use-after-free fix for concurrent dm_resume and dm_destroy (commit 6a459d8edbdb ("dm cache: Fix UAF in destroy()")) as cache_dtr is not changed.

[PATCH openEuler-1.0-LTS] btrfs: ref-verify: fix use-after-free after invalid ref action
by Yifan Qiao 30 Dec '24

30 Dec '24

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.13-rc2 commit 7c4e39f9d2af4abaf82ca0e315d1fd340456620f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAOH CVE: CVE-2024-56581 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- At btrfs_ref_tree_mod() after we successfully inserted the new ref entry (local variable 'ref') into the respective block entry's rbtree (local variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF, we error out and free the ref entry without removing it from the block entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call btrfs_free_ref_cache(), which iterates over all block entries and then calls free_block_entry() for each one, and there we will trigger a use-after-free when we are called against the block entry to which we added the freed ref entry to its rbtree, since the rbtree still points to the block entry, as we didn't remove it from the rbtree before freeing it in the error path at btrfs_ref_tree_mod(). Fix this by removing the new ref entry from the rbtree before freeing it. Syzbot report this with the following stack traces: BTRFS error (device loop0 state EA): Ref action 2, root 5, ref_root 0, parent 8564736, owner 0, offset 0, num_refs 18446744073709551615

[PATCH OLK-6.6] btrfs: ref-verify: fix use-after-free after invalid ref action
by Yifan Qiao 30 Dec '24

30 Dec '24

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.13-rc2 commit 7c4e39f9d2af4abaf82ca0e315d1fd340456620f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAOH CVE: CVE-2024-56581 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- At btrfs_ref_tree_mod() after we successfully inserted the new ref entry (local variable 'ref') into the respective block entry's rbtree (local variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF, we error out and free the ref entry without removing it from the block entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call btrfs_free_ref_cache(), which iterates over all block entries and then calls free_block_entry() for each one, and there we will trigger a use-after-free when we are called against the block entry to which we added the freed ref entry to its rbtree, since the rbtree still points to the block entry, as we didn't remove it from the rbtree before freeing it in the error path at btrfs_ref_tree_mod(). Fix this by removing the new ref entry from the rbtree before freeing it. Syzbot report this with the following stack traces: BTRFS error (device loop0 state EA): Ref action 2, root 5, ref_root 0, parent 8564736, owner 0, offset 0, num_refs 18446744073709551615

[PATCH OLK-5.10] btrfs: ref-verify: fix use-after-free after invalid ref action
by Yifan Qiao 30 Dec '24

30 Dec '24

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.13-rc2 commit 7c4e39f9d2af4abaf82ca0e315d1fd340456620f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAOH CVE: CVE-2024-56581 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- At btrfs_ref_tree_mod() after we successfully inserted the new ref entry (local variable 'ref') into the respective block entry's rbtree (local variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF, we error out and free the ref entry without removing it from the block entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call btrfs_free_ref_cache(), which iterates over all block entries and then calls free_block_entry() for each one, and there we will trigger a use-after-free when we are called against the block entry to which we added the freed ref entry to its rbtree, since the rbtree still points to the block entry, as we didn't remove it from the rbtree before freeing it in the error path at btrfs_ref_tree_mod(). Fix this by removing the new ref entry from the rbtree before freeing it. Syzbot report this with the following stack traces: BTRFS error (device loop0 state EA): Ref action 2, root 5, ref_root 0, parent 8564736, owner 0, offset 0, num_refs 18446744073709551615

[PATCH openEuler-22.03-LTS-SP1] btrfs: ref-verify: fix use-after-free after invalid ref action
by Yifan Qiao 30 Dec '24

30 Dec '24

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.13-rc2 commit 7c4e39f9d2af4abaf82ca0e315d1fd340456620f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAOH CVE: CVE-2024-56581 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- At btrfs_ref_tree_mod() after we successfully inserted the new ref entry (local variable 'ref') into the respective block entry's rbtree (local variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF, we error out and free the ref entry without removing it from the block entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call btrfs_free_ref_cache(), which iterates over all block entries and then calls free_block_entry() for each one, and there we will trigger a use-after-free when we are called against the block entry to which we added the freed ref entry to its rbtree, since the rbtree still points to the block entry, as we didn't remove it from the rbtree before freeing it in the error path at btrfs_ref_tree_mod(). Fix this by removing the new ref entry from the rbtree before freeing it. Syzbot report this with the following stack traces: BTRFS error (device loop0 state EA): Ref action 2, root 5, ref_root 0, parent 8564736, owner 0, offset 0, num_refs 18446744073709551615

[PATCH OLK-6.6] ksmbd: fix use-after-free in SMB request handling

30 Dec '24

From: Yunseong Kim <yskelg(a)gmail.com> mainline inclusion from mainline-v6.13-rc1 commit 9a8c5d89d327ff58e9b2517f8a6afb4181d32c6e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAF6 CVE: CVE-2024-53186 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- A race condition exists between SMB request handling in `ksmbd_conn_handler_loop()` and the freeing of `ksmbd_conn` in the workqueue handler `handle_ksmbd_work()`. This leads to a UAF. - KASAN: slab-use-after-free Read in handle_ksmbd_work - KASAN: slab-use-after-free in rtlock_slowlock_locked This race condition arises as follows: - `ksmbd_conn_handler_loop()` waits for `conn->r_count` to reach zero: `wait_event(conn->r_count_q, atomic_read(&conn->r_count) == 0);` - Meanwhile, `handle_ksmbd_work()` decrements `conn->r_count` using `atomic_dec_return(&conn->r_count)`, and if it reaches zero, calls `ksmbd_conn_free()`, which frees `conn`. - However, after `handle_ksmbd_work()` decrements `conn->r_count`, it may still access `conn->r_count_q` in the following line: `waitqueue_active(&conn->r_count_q)` or `wake_up(&conn->r_count_q)` This results in a UAF, as `conn` has already been freed. The discovery of this UAF can be referenced in the following PR for syzkaller's support for SMB requests.

[PATCH OLK-5.10] drm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'
by Bowen You 30 Dec '24

30 Dec '24

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> mainline inclusion from mainline-v6.12-rc1 commit 63de35a8fcfca59ae8750d469a7eb220c7557baf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAOC CVE: CVE-2024-56608 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- An issue was identified in the dcn21_link_encoder_create function where an out-of-bounds access could occur when the hpd_source index was used to reference the link_enc_hpd_regs array. This array has a fixed size and the index was not being checked against the array's bounds before accessing it. This fix adds a conditional check to ensure that the hpd_source index is within the valid range of the link_enc_hpd_regs array. If the index is out of bounds, the function now returns NULL to prevent undefined behavior.

[PATCH OLK-5.10 1/2] dm cache: fix flushing uninitialized delayed_work on cache_ctr error

From: Ming-Hung Tsai <mtsai(a)redhat.com> stable inclusion from stable-v6.6.61 commit 8cc12dab635333c4ea28e72d7b947be7d0543c2c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5AVP CVE: CVE-2024-50280 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 135496c208ba26fd68cdef10b64ed7a91ac9a7ff upstream. An unexpected WARN_ON from flush_work() may occur when cache creation fails, caused by destroying the uninitialized delayed_work waker in the error path of cache_create(). For example, the warning appears on the superblock checksum error.
