net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not properly manage the relationship between a lock and a socket, which allows local users to cause a denial of service (deadlock) via a crafted sctp_accept call.
A race condition flaw was found in the way the Linux kernel's SCTP implementation handled sctp_accept() during the processing of heartbeat timeout events. A remote attacker could use this flaw to prevent further connections to be accepted by the SCTP server running on the system, resulting in a denial of service.

CVE-2015-8767 [MEDIUM] CVE-2015-8767 kernel: SCTP denial of service during timeout
CVE-2015-8767 kernel: SCTP denial of service during timeout
From the git commit:
An deadlock condition can occur when sctp_accept() is called by the
local software during a heartbeat timeout event after the 4-way handshake. Since sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
bh_sock_lock in sctp_generate_heartbeat_event() will be taken with
the listening socket but released with the new association socket.
The result is a deadlock on any future attempts to take the listening
socket lock, preventing sctp sockets from working correctly.
The server must be running an service using the sctp protocol to be affected.
