Affected files ============== The file(s) affected by this issue are: drivers/soc/rockchip/grf.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/d5422f323858cad3ac3581075f9a3a5e0d41c0d8 https://git.kernel.org/stable/c/28133325526b92921f3269fdf97a20d90b92b217 https://git.kernel.org/stable/c/69a30b2ed620c2206cbbd1e9c112e4fc584e02bd https://git.kernel.org/stable/c/5b3e990f85eb034faa461e691e719e8ce9e2a3c8 https://git.kernel.org/stable/c/aab25b669cb9fd3698c2631be4435f4fe92d9e59 https://git.kernel.org/stable/c/042571fe1d171773655ad706715ecc865913d9a4 https://git.kernel.org/stable/c/8f64e84924604bb969ee1fbc4b8d7d09b9214889 https://git.kernel.org/stable/c/9b59588d8be91c96bfb0371e912ceb4f16315dbf
