CVE-2026-99082

The Linux kernel contains a vulnerability in KVM x86 where the per-vCPU MMIO cache fails to use active memslots. Specifically, the kvm_memslots() helper unconditionally selects address space 0, even when a vCPU is running in SMM (address space 1). This allows an update to SMM memslots to leave st...
