EUVD-2026-25485

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-2026-31590

The CVE-2026-31590 issue affects the Linux kernel KVM SEV path: sev_pin_memory() would WARN when npages overflowed an int due to KVM_MEMORY_ENCRYPT_REG_REGION with a large size, enabling a local user to trigger a harmless warning via userspace input (e.g., addr=0, size=-1ul). The root cause is th...
