NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by Centos.

A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows a local user to crash or potentially cause a denial of service.
