Overview

What is CVE-2026-80532?

In the Linux kernel, the following vulnerability has been resolved:

xfs: fix another iunlink infinite loop bug in online fsck

xrep_iunlink_resolve_bucket is supposed to reconstruct as much of the incore prev and next unlinked list pointers based on what it finds on disk and in memory before we move on to relinking the truly lost inodes back into the unlinked list. However, it's still vulnerable to infinite loops that come in via the next_unlinked pointers.

Fix this problem by remembering which inodes we've already seen and checking new agino pointers against that. If a bit is already set, either this is a loop or the inode has nonzero link count.

We'll deal with the second case in a subsequent patch.
