[PATCH openEuler-1.0-LTS] mm: shmem: don't truncate page if memory failure happens
by Tong Tiangen 27 Dec '24

27 Dec '24

From: Yang Shi <shy828301(a)gmail.com> stable inclusion from stable-v5.15.80 commit 94fa250ea55cd4eea8049011ea4045343547ebd8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBE6C6 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a7605426666196c5a460dd3de6f8dac1d3c21f00 upstream. The current behavior of memory failure is to truncate the page cache regardless of dirty or clean. If the page is dirty the later access will get the obsolete data from disk without any notification to the users. This may cause silent data loss. It is even worse for shmem since shmem is in-memory filesystem, truncating page cache means discarding data blocks. The later read would return all zero. The right approach is to keep the corrupted page in page cache, any later access would return error for syscalls or SIGBUS for page fault, until the file is truncated, hole punched or removed. The regular storage backed filesystems would be more complicated so this patch is focused on shmem. This also unblock the support for soft offlining shmem THP.

[PATCH] ALSA: usb-audio: Fix out of bounds reads when finding clock sources
by Luo Gengkun 27 Dec '24

27 Dec '24

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v5.10.231 commit 45a92cbc88e4013bfed7fd2ccab3ade45f8e896b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHGG CVE: CVE-2024-53150 Reference: https://git.kernel.org/stable/c/45a92cbc88e4013bfed7fd2ccab3ade45f8e896b -------------------------------- commit a3dd4d63eeb452cfb064a13862fb376ab108f6a6 upstream. The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.64 commit 74cb86e1006c5437b1d90084d22018da30fddc77 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHGG CVE: CVE-2024-53150 Reference: https://git.kernel.org/stable/c/74cb86e1006c5437b1d90084d22018da30fddc77 commit a3dd4d63eeb452cfb064a13862fb376ab108f6a6 upstream. The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.

[PATCH OLK-5.10] media: v4l2-tpg: prevent the risk of a division by zero

As reported by Coverity, the logic at tpg_precalculate_line() blindly rescales the buffer even when scaled_witdh is equal to zero. If this ever happens, this will cause a division by zero. Instead, add a WARN_ON_ONCE() to trigger such cases and return without doing any precalculation.

[PATCH OLK-5.10] x86/sgx: Fix deadlock in SGX NUMA node search
by Zhao Yipeng 26 Dec '24

26 Dec '24

From: Aaron Lu <aaron.lu(a)intel.com> mainline inclusion from mainline-v6.12-rc1 commit 9c936844010466535bd46ea4ce4656ef17653644 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYQRL CVE: CVE-2024-49856 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- x86/sgx: Fix deadlock in SGX NUMA node search When the current node doesn't have an EPC section configured by firmware and all other EPC sections are used up, CPU can get stuck inside the while loop that looks for an available EPC page from remote nodes indefinitely, leading to a soft lockup. Note how nid_of_current will never be equal to nid in that while loop because nid_of_current is not set in sgx_numa_mask. Also worth mentioning is that it's perfectly fine for the firmware not to setup an EPC section on a node. While setting up an EPC section on each node can enhance performance, it is not a requirement for functionality. Rework the loop to start and end on *a* node that has SGX memory. This avoids the deadlock looking for the current SGX-lacking node to show up in the loop when it never will.

[PATCH OLK-5.10] printk: Fix the qspinlock deadloop caused by zap_locks()
by Li Huafei 26 Dec '24

26 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBC1RM CVE: NA -------------------------------- printk calls zap_locks() to bypass logbuf_lock during panic. If the current system uses qspinlock, it may cause a deadloop in queued_spin_lock_slowpath(). Consider the following locking sequence: cpu1: (0, 0, 1) cpu2: (0, 1, 1) cpu3: (3, 1, 1) If zap_locks() is called at this time, cpu2 may acquire the lock first, and then cpu3 acquires the lock. When cpu3 releases the lock, it checks if the tail is itself. Originally, it should be, but after zap_locks(), the tail is modified to 0. At this point, cpu3 thinks there are other contenders, it will first set the locked bit and then wait for the contender to set its next pointer. However, in reality, there are no other contenders, so cpu3 will hold the lock (locked bit is 1) and loop here, causing other CPUs that want to acquire the lock to be stuck. To fix this problem, the lock initialization in zap_locks() can be degraded to clear locked_pending and retain the tail, avoiding misjudgment.
