Affected files ============== The file(s) affected by this issue are: drivers/thermal/thermal_hwmon.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/2434f4765da8ccd7ef31be88b86f1bfa2e95be11 https://git.kernel.org/stable/c/b4c01ae6dd56d9dfd96bd1b29c28afa8fa06b366 https://git.kernel.org/stable/c/999e573212d5f1debf073c68be35e55bbfad12fc https://git.kernel.org/stable/c/6a48ee9a5bda0f8ee501f9bef159fb9f39ff519a https://git.kernel.org/stable/c/8d34019d1413629a434a7e8d9f91c76d256196a0 https://git.kernel.org/stable/c/6b446d335ba16e93a266dd77adf1ba51abc82df4 https://git.kernel.org/stable/c/ff8da20b6f47c48d46e47f93f7a59e2d56ee9107
