CVE-2018-5803

Published: 6 March 2018

In the Linux Kernel before version 4.15.8, 4.14.25, 4.9.87, 4.4.121, 4.1.51, and 3.2.102, an error in the "_sctp_make_chunk()" function (net/sctp/sm_make_chunk.c) when handling SCTP packets length can be exploited to cause a kernel crash.

From the Ubuntu Security Team

It was discovered that the SCTP Protocol implementation in the Linux kernel did not properly validate userspace provided payload lengths in some situations. A local attacker could use this to cause a denial of service (system crash).
