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 the possible bioc_list
memory leak during error There are two possible ways to leak bioc memory on
btrfs_ordered_extent::bioc_list: - An error occurred for btrfs_insert_one_raid_extent() Then the function
btrfs_insert_raid_extent() immediately return without freeing any bioc in the bioc_list. - An ordered
extent hit an IO error In that case the ordered extent will have BTRFS_ORDERED_IOERR set, and skip the
call on btrfs_insert_raid_extent() completely. Fix the problem by: - Introduce a new helper,
btrfs_cleanup_ordered_bioc_list() Which will remove all bioc from the bioc_list, and release the bioc. -
Call the above helper for btrfs_insert_raid_extent() So that the cleanup helper is always called no matter
what. - Call the above helper for btrfs_finish_one_ordered() This is called just before the final release
on the ordered extent. This was reported by Sashiko when reviewing another patch. (CVE-2026-98082)
