CVE-2026-72286

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV and Secure Nested Paging SNP virtual machines. The intra-host migration and mirroring feature is not fully implemented for SEV-SNP VMs. This incomplete implementation means that critic...

CVE-2026-72239

A flaw was found in the Linux kernel, specifically within the Secure Encrypted Virtualization-Secure Nested Paging SEV-SNP feature. This vulnerability involves a timing issue, or race condition, during the process of clearing processor caches. If not handled correctly, this can lead to a situatio...
