From version 21.0 to before version 51.2, a guest can cause a use-after-free in the cloud-hypervisor process by submitting two virtio-block descriptor chains that reuse the same head_index while asynchronous block I/O is enabled (e.g. io_uring, aio). When the kernel completes the duplicate operation before the original, the completion path frees a bounce buffer that the kernel is still actively reading from or writing to, corrupt"},"products":[{"@id":"cpe:2.3:a:cloud-hypervisor:cloud-hypervisor:\\>\\=_21.0\\,_\\<_51.2:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:cloud-hypervisor:cloud-hypervisor:\\>\\=_21.0\\,_\\<_51.2:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-10T16:32:33.406Z"}]}
