An issue exists in the KVM arm64 nv component regarding the handling of XN[0] when FEAT XNX is not present. The use of the
FIELD PREP() function on the mask intended to clear XN[0] is incorrect because XN had already been extracted from its bitfield position. This error results in execute permissions being granted unconditionally.Recommendations
