Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.236.26

high Tenable Self-Hosted Container Security Plugin ID 451352

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: ext4: avoid use-after-free in
 ext4_ext_show_leaf() 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. (CVE-2024-49889)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.236.26 or later.
