CVE-2026-80534

Published Aug 26, 2026 EPSS 0.18% (7th pctl)

Overview

CVE-2026-80534 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: fix ilock leak on error in xfs_dq_get_next_id

xfs_dq_get_next_id() takes the quota inode ILOCK before calling

xfs_iread_extents(). If xfs_iread_extents() fails, the function returns

immediately without releasing the lock, leaking the quota inode ILOCK.

This can leave the quota inode locked and cause subsequent quota

operations to hang.

Fix this by jumping to a common unlock path on error instead of returning

directly.

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.
