CVE-2026-80532

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xfs: fix another iunlink infinite loop bug in online fsck<br /> <br /> xrep_iunlink_resolve_bucket is supposed to reconstruct as much of the<br /> incore prev and next unlinked list pointers based on what it finds on<br /> disk and in memory before we move on to relinking the truly lost inodes<br /> back into the unlinked list. However, it&amp;#39;s still vulnerable to infinite<br /> loops that come in via the next_unlinked pointers.<br /> <br /> Fix this problem by remembering which inodes we&amp;#39;ve already seen and<br /> checking new agino pointers against that. If a bit is already set,<br /> either this is a loop or the inode has nonzero link count. We&amp;#39;ll deal<br /> with the second case in a subsequent patch.
