Affected files ============== The file(s) affected by this issue are: drivers/thermal/intel/intel_quark_dts_thermal.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/0b366c6a42e2e2bc67af8d1130b68f3bfa31c80e https://git.kernel.org/stable/c/d0178f2788fb1183a5cc350213efdc94010b9147 https://git.kernel.org/stable/c/e23f1d9e6e03d04da2f18e78ab5d4255ffeb1333 https://git.kernel.org/stable/c/f73134231fa23e0856c15010db5f5c03693c1e92 https://git.kernel.org/stable/c/5eaf55b38691291d49417c22e726591078ca1893 https://git.kernel.org/stable/c/69e49f1b53605706bc2203455021539aba2ebe21 https://git.kernel.org/stable/c/24c221b11c2894e1a5f07b93362d9bc91c6d8be7 https://git.kernel.org/stable/c/f1b930e740811d416de4d2074da48b6633a672c8
