A flaw was found in the Linux kernel's netfilter flowtable component. This vulnerability arises from an error in how the system sets up tunnel routes, specifically in handling network packet encapsulation and tunnel information. An attacker could potentially exploit this to cause incorrect network traffic routing or unexpected packet behavior. This could lead to network disruptions or a denial of service (DoS).
