SUSE CVE-2026-31592

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Protect all of sevmemencregisterregion with kvm-lock Take and hold kvm-lock for before checking sevguest in sevmemencregisterregion, as sevguest isn't stable unless kvm-lock is held or KVM can guarantee KVMSEVINIT2 has...

CVE-2026-31593

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine virtualization module. When Secure Nested Paging SNP is enabled, an attempt to update the state of an already running and encrypted virtual machine can cause the host system to crash. This vulnerability leads to a Denial of...
