CVE-2026-74516

A flaw was found in KVM Kernel-based Virtual Machine. When the Advanced Virtual Interrupt Controller AVIC is inhibited while a nested guest L2 is active, KVM fails to properly update x2APIC MSR intercepts for the primary guest L1. This allows the L1 guest to read the host's APIC state, send...

CVE-2026-74516

The CVE-2026-74516 issue affects the Linux kernel (KVM/SMV) where, if AVIC is inhibited while L2 is active, the host may run L1 with AVIC disabled and with x2APIC MSR intercepts also disabled. This allows L1 to access the host APIC state, trigger arbitrary interrupts, modify task priority, and co...
