[PATCH openEuler-1.0-LTS] dm raid: fix accesses beyond end of raid member array
by Yuan Can 08 Apr '25

08 Apr '25

From: Heinz Mauelshagen <heinzm(a)redhat.com> stable inclusion from stable-v4.19.251 commit df1a5ab0dd0775f2ea101c71f2addbc4c0ea0f85 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP60S CVE: CVE-2022-49674 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 332bd0778775d0cf105c4b9e03e460b590749916 upstream. On dm-raid table load (using raid_ctr), dm-raid allocates an array rs->devs[rs->raid_disks] for the raid device members. rs->raid_disks is defined by the number of raid metadata and image tupples passed into the target's constructor. In the case of RAID layout changes being requested, that number can be different from the current number of members for existing raid sets as defined in their superblocks. Example RAID layout changes include: - raid1 legs being added/removed - raid4/5/6/10 number of stripes changed (stripe reshaping) - takeover to higher raid level (e.g. raid5 -> raid6) When accessing array members, rs->raid_disks must be used in control loops instead of the potentially larger value in rs->md.raid_disks. Otherwise it will cause memory access beyond the end of the rs->devs array. Fix this by changing code that is prone to out-of-bounds access. Also fix validate_raid_redundancy() to validate all devices that are added. Also, use braces to help clean up raid_iterate_devices(). The out-of-bounds memory accesses was discovered using KASAN. This commit was verified to pass all LVM2 RAID tests (with KASAN enabled).

[PATCH OLK-6.6] ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()

From: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> stable inclusion from stable-v6.6.80 commit 2b3878baf90918a361a3dfd3513025100b1b40b6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBSW0Q CVE: CVE-2025-21847 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d8d99c3b5c485f339864aeaa29f76269cc0ea975 upstream. The nullity of sps->cstream should be checked similarly as it is done in sof_set_stream_data_offset() function. Assuming that it is not NULL if sps->stream is NULL is incorrect and can lead to NULL pointer dereference.

[PATCH openEuler-1.0-LTS] wifi: brcmfmac: Check the count value of channel spec to prevent out-of-bounds reads
by Ye Bin 08 Apr '25

08 Apr '25

From: Minsuk Kang <linuxlovemin(a)yonsei.ac.kr> mainline inclusion from mainline-v6.2-rc1 commit 4920ab131b2dbae7464b72bdcac465d070254209 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBWVYB CVE: CVE-2022-49740 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This patch fixes slab-out-of-bounds reads in brcmfmac that occur in brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count value of channel specifications provided by the device is greater than the length of 'list->element[]', decided by the size of the 'list' allocated with kzalloc(). The patch adds checks that make the functions free the buffer and return -EINVAL if that is the case. Note that the negative return is handled by the caller, brcmf_setup_wiphybands() or brcmf_cfg80211_attach(). Found by a modified version of syzkaller.
