REDHAT-BUG-2063257
First published: Fri Mar 11 2022(Updated: )
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.
