In the Linux kernel, the following vulnerability has been resolved: KVM: guestmemfd: Treat memslot binding offset+size as unsigned values When binding a memslot to a guestmemfd file, treat the offset and size as unsigned values to fix a bug where the sum of the two can result in a false negative...

CVE-2026-64283

CVE-2026-64283 : In the Linux kernel KVM guest_memfd binding, the offset and size for a memslot were treated inconsistently (signed/unsigned), enabling a potential overflow-related bypass where an extremely large positive offset plus size could be misinterpreted as smaller than the file size. The...
