Qemu: 9pfs: improper access control on special files

CVSS 6 MEDIUMEPSS 0.4%CWE-284

A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. The 9pfs server did not prohibit opening special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a device file in the shared folder.
