CVE-2026-80665

This vulnerability affects the Linux kernel's KVM arm64 nested virtualization subsystem. The root cause is in kvm_handle_vncr_abort() , which incorrectly assumes that a -EFAULT return from kvm_translate_vncr() always conveys an abort. In practice, "late" failures on S1 translation output (e.g., a...
