The patch for this seems to be here: http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=babd03fde68093482528010a5435c14ce9128e3f So if I understand this correctly.
To exploit this flaw, an attacker would need:
1) A physical USB device plugged into the host machine
2) The USB device "attached" to a guest or the attacker has access to
libvirtd and can attach a USB device.
3) Enough access to the guest to trigger the buffer overflow (root)
From what I can tell, without spending too much time on this, it's very
likely exploitable. I don't think we can prove it's not, as this will end
up overwriting a bunch of global structures, which would have a rather
unknown result.
Presuming my above alalysis is correct, this flaw is probably moderate.
