CVE-2026-80921

CVE-2026-80921 affects the Linux kernel in the KVM s390 vsie (Virtual SIE) subsystem. When shadowing crypto access bits from a format0 apcb (crycb 0 or 1), bits 64–255 retain stale values from the vsie page, potentially allowing a nested guest to access a device no longer available . The CVSS 3.1...

CVE-2026-80921 KVM: s390: vsie: zero stale crypto bits

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...
