CWE-476  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.1 or higher.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. 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.
