CVE-2015-3212

Published: 30 June 2015

Race condition in net/sctp/socket.c in the Linux kernel before 4.1.2 allows local users to cause a denial of service (list corruption and panic) via a rapid series of system calls related to sockets, as demonstrated by setsockopt calls.

From the Ubuntu security team

Marcelo Ricardo Leitner discovered a race condition in the Linux kernel's SCTP address configuration lists when using Address Configuration Change (ASCONF) options on a socket. An unprivileged local user could exploit this flaw to cause a denial of service (system crash).
