  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: psp: do not inherit the Rx association on clone  sk-\u003epsp_assoc sits past sk_dontcopy_end, so sock_copy() copies it into every socket accepted from a listener without taking a reference, while inet_sock_destruct() puts for every inet socket. psp_twsk_init() does refcount_inc() for the timewait socket, so a child closing through TIME_WAIT cancels its own put and leaves the association with one reference and N timewait sockets holding the same pointer. Closing the listener frees it, and the timewait timers then put freed memory.  Rejecting the association on a listening socket is not sufficient: a socket can acquire one while established and then be turned back into a listener, because tcp_disconnect() leaves sk-\u003epsp_assoc in place.
