NVDhttps://nvd.nist.gov/vuln/detail/CVE-2011-4594
CWEhttps://cwe.mitre.org/data/definitions/476.html

The __sys_sendmsg function in net/socket.c in the Linux kernel before 3.1 allows local users to cause a denial of service (system crash) via crafted use of the sendmmsg system call, leading to an incorrect pointer dereference.

Weakness

The product dereferences a pointer that it expects to be valid but is NULL.
