CVE-2026-72284

CVE-2026-72284 affects the Linux kernel KVM on x86, where a logic error in arch/x86/kvm/lapic.c (line ~3338) caused PV EOIs to be ignored if the vCPU later disables PV EOIs, potentially triggering a kernel oops (invalid opcode) during KVM vCPU ioctls. The vulnerability is locally exploitable as p...
