Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/aeroflex/greth.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/223654e2e2c8d05347cd8e300f8d1ec6023103dd https://git.kernel.org/stable/c/cb1e293f858e5e1152b8791047ed4bdaaf392189 https://git.kernel.org/stable/c/bfaa8f6c5b84b295dd73b0138b57c5555ca12b1c https://git.kernel.org/stable/c/99669d94ce145389f1d6f197e6e18ed50d43fb76 https://git.kernel.org/stable/c/87277bdf2c370ab2d07cfe77dfa9b37f82bbe1e5 https://git.kernel.org/stable/c/c7adcbd0fd3fde1b19150c3e955fb4a30c5bd9b7 https://git.kernel.org/stable/c/dd62867a6383f78f75f07039394aac25924a3307 https://git.kernel.org/stable/c/063a932b64db3317ec020c94466fe52923a15f60
