CVE-2026-98716
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Use the active VMCB's MSR bitmap when checking if MSR is intercepted
Use the MSR permission bitmap of the active VMCB instead of assuming that
KVM is always using vmcb02's bitmap when L2 is active, as KVM uses msrpm02
if and only if L1 wants to intercept MSR accesses, i.e. if and only if KVM
needs to merge msprm01 with msrpm12.
Don't bother tracking the virtual address of the bitmap that's being used,
as __va() is cheap on x86, and caching the virtual address would introduce
yet another source of potentially stale information.
