CVE-2026-53200

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for ARM64 architectures. This vulnerability arises from incorrect handling of the Execute Never XN bit, a memory protection feature, when the FEATXNX feature is not enabled. This error can lead to execute permissions being...
