CVE-2016-9106 Qemu: 9pfs: memory leakage in v9fs_write
Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to a memory leakage issue. It
could occur when calling v9fs_write call.
A privileged user inside guest could use this flaw to leak the host memory
bytes resulting in DoS for other services.
