Affected files ============== The file(s) affected by this issue are: drivers/clk/mediatek/clk-mt7629-eth.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/cfa68e0ac5dcde43577adadf6f0f26f3b365ad68 https://git.kernel.org/stable/c/96e9544a0c4faca616b3f9f4034dcd83a14e7f22 https://git.kernel.org/stable/c/c4070ada5d5155c8d4d17ea64bd246949889f25b https://git.kernel.org/stable/c/a540ca0aeae83c2f3964bcb4e383f64ce2ec1783 https://git.kernel.org/stable/c/b20cfe007a46f8c165d42a05c50a8d3d893e6592 https://git.kernel.org/stable/c/1639072f6260babd017556e9f236ca2ad589d1e7 https://git.kernel.org/stable/c/0884393c63cc9a1772f7121a6645ba7bd76feeb9
