CVE-2026-99082 KVM: x86: Use active memslots for the per-vCPU MMIO cache

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use active memslots for the per-vCPU MMIO cache KVM tags the per-vCPU MMIO cache with a memslot generation so that a memslot update invalidates cached MMIO information. Both the fill and validation paths use kvmmemslots...

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 helpers kvm_memslots() unconditionally select address space 0, failing to account for cases where the vCPU is running in SMM using address space 1. This allows an upd...
