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: f2fs: use global inline_xattr_slab
 instead of per-sb slab cache As Hong Yun reported in mailing list: loop7: detected capacity change from 0
 to 131072 ------------[ cut here ]------------ kmem_cache of name 'f2fs_xattr_entry-7:7' already exists

 scripts: - mount /dev/vdb /mnt1 - mount /dev/vdc /mnt2 - umount /mnt1 - mounnt /dev/vdb /mnt1 The reason
 is if we created two slab caches, named f2fs_xattr_entry-7:3 and f2fs_xattr_entry-7:7, and they have the
 same slab size. Actually, slab system will only create one slab cache core structure which has slab name
 of "f2fs_xattr_entry-7:3", and two slab caches share the same structure and cache address. So, if we
 destroy f2fs_xattr_entry-7:3 cache w/ cache address, it will decrease reference count of slab cache,
 rather than release slab cache entirely, since there is one more user has referenced the cache. Then, if
 we try to create slab cache w/ name "f2fs_xattr_entry-7:3" again, slab system will find that there is
 existed cache which has the same name and trigger the warning. Let's changes to use global
 inline_xattr_slab instead of per-sb slab cache for fixing. (CVE-2025-71105)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
