critical
Description
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Sign-extend VA for range-based TLBI invalidation When the decode_range_tlbi() helper was moved to be used for S1 TLBIs, the required sign extension was omitted. Add it. As a result, special care must be taken to not overflow PA bits when this is used for S2 invalidation.
