CVE-2015-7990
Published: 28 December 2015
Race condition in the rds_sendmsg function in net/rds/sendmsg.c in the Linux kernel before 4.3.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6937.
From the Ubuntu security team
Sasha Levin discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel had a race condition when checking whether a socket was bound or not. A local attacker could use this to cause a denial of service (system crash).
