UBUNTU-CVE-2026-64285

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Pin source page for write when adding CPUID data for SNP guest When populating a guestmemfd instance with the initial CPUID data for an SNP guest, acquire a writable pin on the source page as KVM will write back the...

CVE-2026-64285

CVE-2026-64285 affects the Linux kernel KVM SNP guest activity. When populating a guest_memfd’s initial CPUID data, KVM may pin the source page as writable, because KVM writes back CPUID information if userspace data is rejected by trusted firmware. Because the page is accessed via a kernel mappi...
