CVE-2013-1828

The sctp_getsockopt_assoc_stats function in net/sctp/socket.c in the Linux kernel before 3.8.4 does not validate a size value before proceeding to a copy_from_user operation, which allows local users to gain privileges via a crafted application that contains an SCTP_GET_ASSOC_STATS getsockopt system call.
