kernel: use-after-free Read in vhost_transport_send_pkt

A flaw was found where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect and close function may allow an attacker using the AFVSOCK protocol to gather a 4 byte information leak or possibly impersonate AFVSOCK messages...

CVE-2019-18960

Firecracker vsock implementation buffer overflow in versions 0.18.0 and 0.19.0. This can result in potentially exploitable crashes...
