Title
virtio/vsock: Fix accept_queue memory leak
Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio/vsock: Fix accept_queue memory leak
As the final stages of socket destruction may be delayed, it is possible
that virtio_transport_recv_listen() will be called after the accept_queue
has been flushed, but before the SOCK_DONE flag has been set. As a result,
sockets enqueued after the flush would remain unremoved, leading to a
memory leak.
vsock_release
__vsock_release
lock
virtio_transport_release
virtio_transport_close
schedule_delayed_work(close_work)
sk_shutdown = SHUTDOWN_MASK

release
close_work
lock
virtio_transport_do_close
set_flag(SOCK_DONE)

vsock_remove_bound
release
Introduce a sk_shutdown check to disallow vsock_enqueue_accept() during
socket destruction.
