CVE-2022-50817

A flaw was found in the Linux kernel’s High-availability Seamless Redundancy (HSR) network subsystem. When the helper function create_stripped_skb_hsr() returns NULL, the subsequent call to skb_clone() occurs without validating the returned pointer, leading to a potential NULL pointer dereference. Under certain conditions this could cause a kernel crash (denial of service) affecting systems handling HSR traffic.
