  "details": "In the Linux kernel, the following vulnerability has been resolved:  xfs: fix cursor and pointer handling when recovering iunlink buckets  LOLLM pointed out a bug in xlog_recover_iunlink_bucket:  1. We don't null out prev_ip after releasing it, which can lead to UAF    problems if the inodegc flush call in the loop fails.  at which point I noticed even more bugs:  2. If the inodegc flush inside the loop fails, we also leak @ip.  3. We set prev_agino to agino having already advanced agino, which    results in inodes with i_prev_unlinked set to itself.  4. If we exit the bottom of the loop with prev_ip set, then prev_ip    aliases ip and we also set its i_prev_unlinked to itself.  Bugs 3 and 4 introduce loops into the unlinked list, though these loops don't surface because we immediately flush each unlinked inode after loading it.  Fix all of these issues.",
