Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/pensando/ionic/ionic_lif.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/4c7276a6daf7e13a6dd30b0347b3f2c7df4d40bb https://git.kernel.org/stable/c/f8cc4fd99a325505e15c3da95d6de266efd3d9b5 https://git.kernel.org/stable/c/1417dd787a5e55b410a00a28231b0dcb19172457 https://git.kernel.org/stable/c/dc470466753ad0dd3a8c48aaefa05a992c119b9c https://git.kernel.org/stable/c/daeaad114cb163ec51bcf14326cb7fe37d368459 https://git.kernel.org/stable/c/abfb2a58a5377ebab717d4362d6180f901b6e5c1
