Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due in the Linux kernels SELinux LSM hook implementation where the kernel incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing.


Remediation

Install updates from vendor's website.
