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: configfs: unhash the dentry before
dropping the item in rmdir configfs_get_config_item() treats a hashed dentry as proof that sd->s_element
is a live config_item. configfs_rmdir() breaks that: simple_rmdir() leaves the dentry hashed, the last
reference to the item is dropped right after, and the dentry is only unhashed by d_delete() once ->rmdir()
has returned. configfs_symlink() resolves its target holding no lock on it, so get_target() can land in
that window: BUG: KASAN: slab-use-after-free in config_item_get+0x26/0x90 get_target
fs/configfs/symlink.c:128 [inline] configfs_symlink+0x4ab/0x1030 fs/configfs/symlink.c:185 Unhash in
configfs_remove_dir(), while the item is still guaranteed to be there. A reference obtained just before
that stays harmless, as create_link() rechecks CONFIGFS_USET_DROPPING, already set by
configfs_detach_prep(). Both configfs_unregister_subsystem() paths d_drop() after detaching, so this only
makes rmdir match them. (CVE-2026-97949)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
