Description

Problem Description: A programming error in processing a TCP connection with both TCP_MD5SIG and TCP_NOOPT socket options may lead to kernel crash. Impact: A local attacker can crash the kernel, resulting in a denial-of-service. A remote attack is theoretically possible, if server has a listening socket with TCP_NOOPT set, and server is either out of SYN cache entries, or SYN cache is disabled by configuration.
