CVE-2026-64282

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Don't leak PFN when kvm_translate_vncr() races MMU notifier In the case that kvm_translate_vncr() races with an MMU notifier the early return does not release a reference on the faulted in PFN. Add the necessary call to kvm_release_faultin_page() for the unused PFN.
