CVE-2026-79611

The Xen hypervisor is vulnerable to a VMEntry failure in HVM/PVH guests using Intel, VIA, or Zhaoxin CPUs (VMX hardware extensions). The issue arises because VMX VMEntry checks do not correctly handle a specific combination of states where #DB is intercepted , Single Stepping is active , and STI/...

CVE-2026-59347
