Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: vsie: zero stale crypto bits
When shadowing crypto access bits from a format0 apcb (crycb 0 or 1), the bits 64..255 are unchanged from whatever is in the vsie page in the crycb and thus in the apcb. This gives a nested guest potential access to a device no longer available. Zero out the remaining bits.
