In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: nv: Fix handling of XN[0] when !FEAT_XNX
XN has already been extracted from its bitfield position so using
FIELD_PREP() on the mask that clears XN[0] is completely broken, having
the effect of unconditionally granting execute permissions...
Fix the obvious mistake by manipulating the right bit.

Fix the obvious mistake by manipulating the right bit.
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 attacke
