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.
