[PATCH OLK-5.10] drm/gma500: fix null pointer dereference in cdv_intel_lvds_get_modes
by Liu Chuang 20 Aug '24

From: Ma Ke <make24(a)iscas.ac.cn> stable inclusion from stable-v5.10.224 commit b6ac46a00188cde50ffba233e6efb366354a1de5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKPXH CVE: CVE-2024-42310 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit cb520c3f366c77e8d69e4e2e2781a8ce48d98e79 upstream. In cdv_intel_lvds_get_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

[PATCH openEuler-22.03-LTS-SP1] ext4: fix infinite loop when replaying fast_commit
by Zhihao Cheng 20 Aug '24

20 Aug '24

From: "Luis Henriques (SUSE)" <luis.henriques(a)linux.dev> mainline inclusion from mainline-v6.11-rc1 commit 907c3fe532253a6ef4eb9c4d67efb71fab58c706 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKQ7X CVE: CVE-2024-43828 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When doing fast_commit replay an infinite loop may occur due to an uninitialized extent_status struct. ext4_ext_determine_insert_hole() does not detect the replay and calls ext4_es_find_extent_range(), which will return immediately without initializing the 'es' variable. Because 'es' contains garbage, an integer overflow may happen causing an infinite loop in this function, easily reproducible using fstest generic/039. This commit fixes this issue by unconditionally initializing the structure in function ext4_es_find_extent_range(). Thanks to Zhang Yi, for figuring out the real problem!
