David Hildenbrand b85de33a1a KVM: s390: avoid memory overwrites on emergency signal injection ... Commit 383d0b0501 ("KVM: s390: handle pending local interrupts via bitmap") introduced a possible memory overwrite from user space. User space could pass an invalid emergency signal code (sending VCPU) and therefore exceed the bitmap. Let's take care of this case and check that the id is in the valid range.
