CVE-2026-3842 Qemu-kvm: hyperv/syndbg: missing mapped-length guard after cpu_physical_memory_map causes host oob write

A flaw was found in QEMU. This vulnerability allows a local attacker within a guest virtual machine to write data beyond its allocated memory. This occurs when cpuphysicalmemorymap returns a shorter length than expected, leading to an out-of-bounds write. Successful exploitation could result in...
