CVE-2026-79610

Unspecified impact via stale grant-status pointers

Published Oct 13, 2026 · Updated Oct 13, 2026

Race condition in Xen grant-table handling allows attackers to cause unspecified impact via repeated grant-table version changes. A version 2-to-1-to-2 transition frees and reallocates status pages, leaving previously calculated status-array pointers stale when page addresses change. The supplied description does not establish required privileges or the resulting security consequence, and the upstream advisory was inaccessible during research.
