Use INIT_LIST_HEAD() on it to initialize it correctly. The Linux kernel CVE team has assigned CVE-2022-48972 to this issue.

Affected files ============== The file(s) affected by this issue are: net/mac802154/iface.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7410f4d1221bb182510b7778ab6eefa8b9b7102d https://git.kernel.org/stable/c/9980a3ea20de40c83817877106c909cb032692d2 https://git.kernel.org/stable/c/f00c84fb1635c27ba24ec5df65d5bd7d7dc00008 https://git.kernel.org/stable/c/1831d4540406708e48239cf38fd9c3b7ea98e08f https://git.kernel.org/stable/c/42c319635c0cf7eb36eccac6cda76532f47b61a3 https://git.kernel.org/stable/c/a110287ef4a423980309490df632e1c1e73b3dc9 https://git.kernel.org/stable/c/623918f40fa68e3bb21312a3fafb90f491bf5358 https://git.kernel.org/stable/c/b3d72d3135d2ef68296c1ee174436efd65386f04
