SUSE CVE-2026-63938

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Check PSC request indices against the actual size of the buffer When processing Page State Change PSC requests, validate the PSC buffer against the effective size of the scratch area, which could be less than the maximu...

SUSE CVE-2026-63939

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Compute the correct max length of the in-GHCB scratch area When setting the length of the GHCB scratch area, and the area is in the GHCB shared buffer, set the effective length of the scratch area to the max possible si...

CVE-2026-63806

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A malicious guest operating system can trigger a host kernel crash, leading to a Denial of Service DoS. This occurs when the guest performs a specific memory write operation that causes an unaligned memory access...
