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: btrfs: fix transaction use-after-free
in raid stripe insertion If allocation of a RAID stripe extent fails, btrfs_insert_one_raid_extent()
aborts and ends the transaction before returning -ENOMEM. btrfs_finish_one_ordered(), the production
caller through btrfs_insert_raid_extent(), still owns the transaction handle. It handles the error by
aborting the transaction and then reaches the common exit path, which ends the transaction again. The
premature end can free the handle and drop its transaction reference. Transaction cleanup can then free
the transaction before the caller's second abort accesses the handle and transaction, resulting in use-
after-free. Keep the abort at the failure site, but let the caller's common exit path end the transaction
once, after it has finished using both objects. (CVE-2026-98083)

Solution

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