CVE-2022-48786 is a Linux kernel AF_VSOCK lifecycle flaw in vsock_connect(). If a task waiting for a connection is interrupted by a pending signal after the socket has reached TCP_ESTABLISHED state, the socket can remain in the vsock connected-socket table while its state is reset. A subsequent successful connect() retry adds the same socket to the connected table again, corrupting the list. The fix removes the socket from the connected table when signal interruption occurs while waiting for the connection.
