Affected files ============== The file(s) affected by this issue are: arch/um/drivers/net_kern.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/b174ab33aaafd556a1ead72fa8e35d70b6fb1e39 https://git.kernel.org/stable/c/8d9d174d3f55daaf5e7b48e9d7f53c723adbed86 https://git.kernel.org/stable/c/6be99d4c117b9642a44d9f54f034b67615be2b2b https://git.kernel.org/stable/c/1635d9a0ff1b8bd7aa4767d4ea7b3de72cd36f28 https://git.kernel.org/stable/c/160cd5f956d191eb97664afd31ca59284c08d876 https://git.kernel.org/stable/c/cdbd5a1dcdc2c27ac076f91b03b9add3fefa1a82 https://git.kernel.org/stable/c/468c2e5394afc848efb1eae6e1961a3c855cf35e https://git.kernel.org/stable/c/f04cd022ee1fde219e0db1086c27a0a5ba1914db https://git.kernel.org/stable/c/d1db692a9be3b4bd3473b64fcae996afaffe8438
