CVE-2026-72279

A flaw was found in the KVM Kernel-based Virtual Machine component of the Linux kernel. KVM on arm64 architectures incorrectly maps the L1 Virtual Nested Control Register VNCR into the host stage-1, failing to respect read-only memory regions. This could allow a malicious guest to write to a...

CVE-2026-72280

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for ARM64 architectures. A guest operating system, when operating in a nested virtualization environment, could trigger a hypervisor panic hyppanic by writing to the ZCREL2 system register alias. This issue leads to a denial ...

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...
