CVE-2019-3874
Published: 25 March 2019
The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable.
From the Ubuntu Security Team
Matteo Croce, Natale Vinto, and Andrea Spagnolo discovered that the cgroups subsystem of the Linux kernel did not properly account for SCTP socket buffers. A local attacker could use this to cause a denial of service (system crash).
