1263139: CVE-2015-6937 kernel: net: rds: NULL pointer dereference in net/rds/connection.c
A NULL-pointer dereference vulnerability was discovered in the Linux kernel. The kernel's Reliable Datagram Sockets (RDS) protocol implementation did not verify that an underlying transport existed before creating a connection to a remote server. A local system user could exploit this flaw to crash the system by creating sockets at specific times to trigger a NULL pointer dereference.
