CVE-2015-5283

Published: 19 October 2015

The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3 has an incorrect sequence of protocol-initialization steps, which allows local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished.

From the Ubuntu Security Team

It was discovered that the SCTP protocol implementation in the Linux kernel performed an incorrect sequence of protocol-initialization steps. A local attacker could use this to cause a denial of service (system crash).
