CVE-2026-6426 Qemu-kvm: vhost inflight migration vmstate integer type mismatch causes out-of-bounds access

A type mismatch vulnerability was found in QEMU's vhost inflight migration VMState handling. The destination buffer size is stored as a uint64t but read by the VMSVBUFFER load path as a signed int32t. On little-endian hosts, a crafted incoming migration state with bit 31 set causes the value to b...

CVE-2026-6426

QEMU's vhost inflight migration VMState handling is affected by a type‑mismatch in the destination buffer size: it is stored as uint64_t but read as signed int32_t. On little‑endian hosts, a crafted incoming migration state with bit 31 set can become negative and be implicitly converted to a very...
