CVE-2026-79610
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...

CVE-2026-79610
The Xen hypervisor is vulnerable to a grant-table double version change race condition (CWE-362). When performing a v2 -> v1 -> v2 change, status pages are freed during the first transition and re-allocated during the second, causing stale pointers in the status array. This may result in pr...
