  "description": "In the Linux kernel, the following vulnerability has been resolved:  net/rose: fix NULL pointer dereference in rose_transmit_link on reconnect  syzkaller reported a bug [1], and the reproducer is available at [2].  ROSE sockets use four sk-\u003Esk_state values: TCP_CLOSE, TCP_LISTEN, TCP_SYN_SENT, and TCP_ESTABLISHED. rose_connect() already rejects calls for TCP_ESTABLISHED (-EISCONN) and TCP_CLOSE with SS_CONNECTING (-ECONNREFUSED), but lacks a check for TCP_SYN_SENT.  When rose_connect() is called a second time while the first connection attempt is still in progress (TCP_SYN_SENT), it overwrites rose-\u003Eneighbour via rose_get_neigh(). If that returns NULL, the socket is left with rose-\u003Estate == ROSE_STATE_1 but rose-\u003Eneighbour == NULL. When the socket is subsequently closed, rose_release() sees ROSE_STATE_1 and calls rose_write_internal() -\u003E rose_transmit_link(skb, NULL), causing a NULL pointer dereference.  Per connect(2), a second connect() while a connection is already in progress should return -EALREADY. Add this missing check for TCP_SYN_SENT to complete the state validation in rose_connect().
