From: Xiang Chen <chenxiang66(a)hisilicon.com> virt inclusion category: other bugzilla: https://gitee.com/openeuler/kernel/issues/I9SGLA ------------------------------------------------------------------ For gicv4.0 of hip09, it has a soc bug with vPE schedule: when multiple vPEs are sending vpe schedule/deschedule commands concurrently and repeatly, some vPE schedule command may not be scheduled, and it will cause the command timeout. To avoid the issue, limit the number of vLPI to 4096 for virtual machine.

[PATCH openEuler-1.0-LTS] comedi: vmk80xx: fix transfer-buffer overflows
by Cai Xinchen 27 May '24

27 May '24

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v4.19.217 commit 7a2021b896de1ad559d33b5c5cdd20b982242088 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD17 CVE: CVE-2021-47475 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a23461c47482fc232ffc9b819539d1f837adf2b1 upstream. The driver uses endpoint-sized USB transfer buffers but up until recently had no sanity checks on the sizes. Commit e1f13c879a7c ("staging: comedi: check validity of wMaxPacketSize of usb endpoints found") inadvertently fixed NULL-pointer dereferences when accessing the transfer buffers in case a malicious device has a zero wMaxPacketSize. Make sure to allocate buffers large enough to handle also the other accesses that are done without a size check (e.g. byte 18 in vmk80xx_cnt_insn_read() for the VMK8061_MODEL) to avoid writing beyond the buffers, for example, when doing descriptor fuzzing. The original driver was for a low-speed device with 8-byte buffers. Support was later added for a device that uses bulk transfers and is presumably a full-speed device with a maximum 64-byte wMaxPacketSize.

[PATCH openEuler-22.03-LTS-SP1] padata: Fix refcnt handling in padata_free_shell()
by Zheng Zucheng 27 May '24

From: WangJinchao <wangjinchao(a)xfusion.com> stable inclusion from stable-v5.10.201 commit 41aad9d6953984d134fc50f631f24ef476875d4d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RQM3 CVE: CVE-2023-52854 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7ddc21e317b360c3444de3023bcc83b85fabae2f ] In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead to system UAF (Use-After-Free) issues. Due to the lengthy analysis of the pcrypt_aead01 function call, I'll describe the problem scenario using a simplified model: Suppose there's a user of padata named `user_function` that adheres to the padata requirement of calling `padata_free_shell` after `serial()` has been invoked, as demonstrated in the following code: ```c struct request { struct padata_priv padata; struct completion *done; }; void parallel(struct padata_priv *padata) { do_something(); } void serial(struct padata_priv *padata) { struct request *request = container_of(padata, struct request, padata); complete(request->done); } void user_function() { DECLARE_COMPLETION(done) padata->parallel = parallel; padata->serial = serial; padata_do_parallel(); wait_for_completion(&done); padata_free_shell(); } ``` In the corresponding padata.c file, there's the following code: ```c static void padata_serial_worker(struct work_struct *serial_work) { ... cnt = 0; while (!list_empty(&local_list)) { ... padata->serial(padata); cnt++; } local_bh_enable(); if (refcount_sub_and_test(cnt, &pd->refcnt)) padata_free_pd(pd); } ``` Because of the high system load and the accumulation of unexecuted softirq at this moment, `local_bh_enable()` in padata takes longer to execute than usual. Subsequently, when accessing `pd->refcnt`, `pd` has already been released by `padata_free_shell()`, resulting in a UAF issue with `pd->refcnt`. The fix is straightforward: add `refcount_dec_and_test` before calling `padata_free_pd` in `padata_free_shell`.

[PATCH openEuler-1.0-LTS v2] net/tls: Fix flipped sign in tls_err_abort() calls
by Ziyang Xuan 25 May '24

25 May '24

From: Daniel Jordan <daniel.m.jordan(a)oracle.com> mainline inclusion from mainline-v5.15 commit da353fac65fede6b8b4cfe207f0d9408e3121105 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RCYN CVE: CVE-2021-47496 -------------------------------- sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

[PATCH openEuler-1.0-LTS] HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
by Yang Yingliang 25 May '24

25 May '24

From: Nam Cao <namcao(a)linutronix.de> mainline inclusion from mainline-v6.9-rc6 commit 9c0f59e47a90c54d0153f8ddc0f80d7a36207d0e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRN6 CVE: CVE-2024-35997 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that.

For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

[PATCH openEuler-1.0-LTS] nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells
by Cai Xinchen 25 May '24

25 May '24

From: Stephen Boyd <swboyd(a)chromium.org> stable inclusion from stable-v4.19.213 commit eb0fc8e7170e61eaf65d28dee4a8baf4e86b19ca category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD7J CVE: CVE-2021-47497 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 5d388fa01fa6eb310ac023a363a6cb216d9d8fe9 upstream. If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic *p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0); will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long. UBSAN reports this problem: UBSAN: shift-out-of-bounds in drivers/nvmem/core.c:1386:8 shift exponent 64 is too large for 64-bit type 'unsigned long' CPU: 6 PID: 7 Comm: kworker/u16:0 Not tainted 5.15.0-rc3+ #9 Hardware name: Google Lazor (rev3+) with KB Backlight (DT) Workqueue: events_unbound deferred_probe_work_func Call trace: dump_backtrace+0x0/0x170 show_stack+0x24/0x30 dump_stack_lvl+0x64/0x7c dump_stack+0x18/0x38 ubsan_epilogue+0x10/0x54 __ubsan_handle_shift_out_of_bounds+0x180/0x194 __nvmem_cell_read+0x1ec/0x21c nvmem_cell_read+0x58/0x94 nvmem_cell_read_variable_common+0x4c/0xb0 nvmem_cell_read_variable_le_u32+0x40/0x100 a6xx_gpu_init+0x170/0x2f4 adreno_bind+0x174/0x284 component_bind_all+0xf0/0x264 msm_drm_bind+0x1d8/0x7a0 try_to_bring_up_master+0x164/0x1ac __component_add+0xbc/0x13c component_add+0x20/0x2c dp_display_probe+0x340/0x384 platform_probe+0xc0/0x100 really_probe+0x110/0x304 __driver_probe_device+0xb8/0x120 driver_probe_device+0x4c/0xfc __device_attach_driver+0xb0/0x128 bus_for_each_drv+0x90/0xdc __device_attach+0xc8/0x174 device_initial_probe+0x20/0x2c bus_probe_device+0x40/0xa4 deferred_probe_work_func+0x7c/0xb8 process_one_work+0x128/0x21c process_scheduled_works+0x40/0x54 worker_thread+0x1ec/0x2a8 kthread+0x138/0x158 ret_from_fork+0x10/0x20 Fix it by making sure there are any bits to mask out.

From: Nicolas Pitre <nico(a)fluxnic.net> stable inclusion from stable-v4.19.312 commit fc7dfe3d123f00e720be80b920da287810a1f37d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q994 CVE: CVE-2024-35823 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 1581dafaf0d34bc9c428a794a22110d7046d186d upstream. This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the buffer"). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers.

[PATCH openEuler-1.0-LTS] ipv6: Fix infinite recursion in fib6_dump_done().
by Zhengchao Shao 25 May '24

25 May '24

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v4.19.312 commit 9472d07cd095cbd3294ac54c42f304a38fbe9bfe category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG76 CVE: CVE-2024-35886 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d21d40605bca7bd5fc23ef03d4c1ca1f48bc2cae upstream. syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

[PATCH OLK-5.10] net: atlantic: eliminate double free in error handling logic

25 May '24

From: Igor Russkikh <irusskikh(a)marvell.com> mainline inclusion from mainline-v6.8-rc1 commit b3cb7a830a24527877b0bc900b9bd74a96aea928 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q919 CVE: CVE-2023-52664 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.

[PATCH OLK-5.10] ipv6: Fix infinite recursion in fib6_dump_done().
by Zhengchao Shao 25 May '24

25 May '24

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v5.10.215 commit fd307f2d91d40fa7bc55df3e2cd1253fabf8a2d6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG76 CVE: CVE-2024-35886 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d21d40605bca7bd5fc23ef03d4c1ca1f48bc2cae upstream. syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

[PATCH OLK-5.10] drm/amdgpu: handle the case of pci_channel_io_frozen only in amdgpu_pci_resume
by Xiongfeng Wang 24 May '24

24 May '24

From: Guchun Chen <guchun.chen(a)amd.com> mainline inclusion from mainline-v5.15-rc5 commit 248b061689a40f4fed05252ee2c89f87cf26d7d8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4NB CVE: CVE-2021-47421 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In current code, when a PCI error state pci_channel_io_normal is detectd, it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI driver will continue the execution of PCI resume callback report_resume by pci_walk_bridge, and the callback will go into amdgpu_pci_resume finally, where write lock is releasd unconditionally without acquiring such lock first. In this case, a deadlock will happen when other threads start to acquire the read lock. To fix this, add a member in amdgpu_device strucutre to cache pci_channel_state, and only continue the execution in amdgpu_pci_resume when it's pci_channel_io_frozen.
