Overview

CVE-2026-79610 is a high-severity vulnerability. It was published on October 13, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

XSA-501 was about issues with v1 -> v2 and v2 -> v1 changes racing certain

other grant table operations. Sadly a v2 -> v1 -> v2 change has yet

another effect which wasn't accounted for: During the first change, status

pages would be freed. During the second change they would be allocated

again. Hence across the full pair of change the addresses of the status

pages may change, rendering stale previously calculated pointers into the

status array.

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.
