[PATCH openEuler-1.0-LTS] ext4: avoid use-after-free in ext4_ext_show_leaf()
by Baokun Li 02 Nov '24

02 Nov '24

stable inclusion from stable-v5.10.227 commit b0cb4561fc4284d04e69c8a66c8504928ab2484e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR98 CVE: CVE-2024-49889 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4e2524ba2ca5f54bdbb9e5153bea00421ef653f5 ] In ext4_find_extent(), path may be freed by error or be reallocated, so using a previously saved *ppath may have been freed and thus may trigger use-after-free, as follows: ext4_split_extent path = *ppath; ext4_split_extent_at(ppath) path = ext4_find_extent(ppath) ext4_split_extent_at(ppath) // ext4_find_extent fails to free path // but zeroout succeeds ext4_ext_show_leaf(inode, path) eh = path[depth].p_hdr // path use-after-free !!! Similar to ext4_split_extent_at(), we use *ppath directly as an input to ext4_ext_show_leaf(). Fix a spelling error by the way. Same problem in ext4_ext_handle_unwritten_extents(). Since 'path' is only used in ext4_ext_show_leaf(), remove 'path' and use *ppath directly. This issue is triggered only when EXT_DEBUG is defined and therefore does not affect functionality.

[PATCH OLK-5.10] drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn30_init_hw

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> mainline inclusion from mainline-v6.12-rc1 commit cba7fec864172dadd953daefdd26e01742b71a6a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR9I CVE: CVE-2024-49917 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This commit addresses a potential null pointer dereference issue in the `dcn30_init_hw` function.
