This improper handling results i...

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 SEV SNP path. When populating a guest’s initial CPUID data, KVM may pin a source page as writable and write back data if the userspace-provided CPUID data is rejected by trusted firmware, risking clobbering read-only memory due to kernel mappings. Multi...
