by Tengda Wu 31 Dec '24

31 Dec '24

From: WangYuli <wangyuli(a)uniontech.com> stable inclusion from stable-v5.10.231 commit 5912a921289edb34d40aeab32ea6d52d41e75fed category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAPQ CVE: CVE-2024-56629 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 59548215b76be98cf3422eea9a67d6ea578aca3d upstream. Due to incorrect dev->product reporting by certain devices, null pointer dereferences occur when dev->product is empty, leading to potential system crashes.

From: WangYuli <wangyuli(a)uniontech.com> stable inclusion from stable-v5.10.231 commit 5912a921289edb34d40aeab32ea6d52d41e75fed category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAPQ CVE: CVE-2024-56629 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 59548215b76be98cf3422eea9a67d6ea578aca3d upstream. Due to incorrect dev->product reporting by certain devices, null pointer dereferences occur when dev->product is empty, leading to potential system crashes.

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.

From: Chuck Lever <chuck.lever(a)oracle.com> stable inclusion from stable-v4.19.325 commit 745f7ce5a95e783ba62fe774325829466aec2aa8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHG9 CVE: CVE-2024-53146 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7f33b92e5b18e904a481e6e208486da43e4dc841 upstream. 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.
