CVE-2026-79610

A flaw was found in Xen. When a guest virtual machine repeatedly changes grant table configurations, the hypervisor frees and reallocates status memory pages, rendering previously calculated pointers invalid. A malicious guest can exploit these stale pointers to corrupt hypervisor memory,...
