"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/rose: fix NULL pointer dereference in rose_transmit_link on reconnect\n\nsyzkaller reported a bug [1], and the reproducer is available at [2].\n\nROSE sockets use four sk->sk_state values: TCP_CLOSE, TCP_LISTEN,\nTCP_SYN_SENT, and TCP_ESTABLISHED. rose_connect() already rejects\ncalls for TCP_ESTABLISHED (-EISCONN) and TCP_CLOSE with SS_CONNECTING\n(-ECONNREFUSED), but lacks a check for TCP_SYN_SENT.\n\nWhen rose_connect() is called a second time while the first connection\nattempt is still in progress (TCP_SYN_SENT), it overwrites\nrose->neighbour via rose_get_neigh(). If that returns NULL, the socket\nis left with rose->state == ROSE_STATE_1 but rose->neighbour == NULL.\nWhen the socket is subsequently closed, rose_release() sees\nROSE_STATE_1 and calls rose_write_internal() ->\nrose_transmit_link(skb, NULL), causing a NULL pointer dereference.\n\nPer connect(2), a second connect() while a connection is already in\nprogress should return -EALREADY. Add this missing check for\nTCP_SYN_SENT to complete the state validation in rose_connect().\n\n[1] https://syzkaller.appspot.com/bug?extid=d00f90e0af54102fb271\n[2] https://gist.github.com/mrpre/9e6779e0d13e2c66779b1653fef80516"
