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.
