kernel: SELinux netlink permission check bypass

A flaw was found in the Linux kernel’s SELinux LSM hook implementation, where it anticipated the skb would only contain a single Netlink message. The hook incorrectly validated the first Netlink message in the skb only, to allow or deny the rest of the messages within the skb with the granted...
