  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvirtio/vsock: Fix accept_queue memory leak\n\nAs the final stages of socket destruction may be delayed, it is possible\nthat virtio_transport_recv_listen() will be called after the accept_queue\nhas been flushed, but before the SOCK_DONE flag has been set.
