The timer is setup in probe and there is no timer_delete operation in remove function. When it hit kfree btv, the function might still be invoked, which will cause use after free bug. This bug is found by static analysis, it may be false positive.

[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.

[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.

[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.

[PATCH openEuler-1.0-LTS] hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs
by Zheng Yejian 24 May '24

24 May '24

From: Vadim Pasternak <vadimp(a)nvidia.com> stable inclusion from stable-v4.19.209 commit 5c6e0bce647d9cb32a17d58ffa669b3421fcc6ca category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4O0 CVE: CVE-2021-47393 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e6fab7af6ba1bc77c78713a83876f60ca7a4a064 ] Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature. Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum. Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS. Here is the trace from KASAN: [ 159.506659] BUG: KASAN: slab-out-of-bounds in thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.516016] Read of size 4 at addr ffff888116163840 by task hw-management.s/7444 [ 159.545625] Call Trace: [ 159.548366] dump_stack+0x92/0xc1 [ 159.552084] ? thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.635869] thermal_zone_device_update+0x345/0x780 [ 159.688711] thermal_zone_device_set_mode+0x7d/0xc0 [ 159.694174] mlxsw_thermal_modules_init+0x48f/0x590 [mlxsw_core] [ 159.700972] ? mlxsw_thermal_set_cur_state+0x5a0/0x5a0 [mlxsw_core] [ 159.731827] mlxsw_thermal_init+0x763/0x880 [mlxsw_core] [ 160.070233] RIP: 0033:0x7fd995909970 [ 160.074239] Code: 73 01 c3 48 8b 0d 28 d5 2b 00 f7 d8 64 89 01 48 83 c8 ff c3 66 0f 1f 44 00 00 83 3d 99 2d 2c 00 00 75 10 b8 01 00 00 00 0f 05 <48> 3d 01 f0 ff ..

[PATCH openEuler-1.0-LTS] ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
by Zhao Mengmeng 24 May '24

24 May '24

From: Jiri Benc <jbenc(a)redhat.com> stable inclusion from stable-v4.19.313 commit b4b3b69a19016d4e7fbdbd1dbcc184915eb862e1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRPL CVE: CVE-2024-35969 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7633c4da919ad51164acbf1aa322cc1a3ead6129 ] Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4.
