EUVD-2026-55840

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...
