"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: check RCV_SHUTDOWN after the sendmsg connect wait\n\nsctp_wait_for_connect() drops the socket lock while it sleeps. An\nout-of-the-blue ABORT can then be processed from the socket backlog and\nunlink the association. If a concurrent shutdown(fd, SHUT_RD) sets\nRCV_SHUTDOWN, the waiter breaks with err == 0 before checking\nasoc->base.dead. Its final sctp_association_put() can then free the\nassociation, leaving sctp_sendmsg_to_asoc() to continue with a dangling\npointer.\n\nCheck RCV_SHUTDOWN along with the wait error in sctp_sendmsg_to_asoc()\nbefore using the association again. The check only accesses the socket,\nso it needs no additional association reference. Return the existing\n-ESRCH so that sctp_sendmsg() skips freeing a new association that may\nalready have been destroyed.\n\nKeep sctp_wait_for_connect() unchanged to preserve its behavior for the\nconnect() caller."
