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.
