| Doc Text: |
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 FEAT_XNX feature is not enabled. This error can lead to execute permissions being unconditionally granted, potentially allowing a local attacker to execute arbitrary code with elevated privileges.
