CVE-2026-80533

Estado: RecibidaSin puntuar—

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

xfs: don't walk off the end of a null sc->sa.agi_bp in AGI repair

LOLLM noticed a longstanding bug where xrep_iunlink_walk_ondisk_bucket tries to walk ragi->sc->sa.agi_bp to rebuild the unlinked inode lists. Unfortunately, it's possible for agi_bp to be null if the buffer verifier fails, so we have to use ragi->agi_bp (which skips verifier checks) instead.
