CVE-2026-80533

Published Aug 26, 2026 EPSS 0.17% (6th pctl)

Overview

CVE-2026-80533 is a known-severity vulnerability. It was published on August 26, 2026.

Technical Description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
