CVE-2015-7990 (retired)

Priority
Description
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.
Ubuntu-Description
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).
