Description

A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it 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.

Affected configurations

• kernel selinux (< 5.7) • redhat enterprise linux server 7.0 • redhat enterprise linux server 8.0
