Description Mauro Matteo Cascella 2022-03-11 16:11:40 UTC 
A flaw was found in the vhost-vsock device of QEMU. In case of error, vhost_vsock_common_send_transport_reset() did not detach the invalid element from the virtqueue before freeing its memory, leading to memory leakage or other unexpected results.
