CVSS 7.800000190734863 HIGH
A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system instability or a denial of service (DoS) condition, where the affected system becomes unresponsive.
