Affected files ============== The file(s) affected by this issue are: drivers/platform/x86/dell/dell-wmi-sysman/dell-wmi-sysman.h drivers/platform/x86/dell/dell-wmi-sysman/enum-attributes.c drivers/platform/x86/dell/dell-wmi-sysman/int-attributes.c drivers/platform/x86/dell/dell-wmi-sysman/passobj-attributes.c drivers/platform/x86/dell/dell-wmi-sysman/string-attributes.c drivers/platform/x86/dell/dell-wmi-sysman/sysman.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/92c2d914b5337431d885597a79a3a3d9d55e80b7 https://git.kernel.org/stable/c/68e9963583d11963ceca5d276e9c44684509f759 https://git.kernel.org/stable/c/0deb3eb78ebf225cb41aa9b2b2150f46cbfd359e https://git.kernel.org/stable/c/5df3b870bc389a1767c72448a3ce1c576ef4deab https://git.kernel.org/stable/c/aaf847dcb4114fe8b25d4c1c790bedcb6088cb3d https://git.kernel.org/stable/c/eb617dd25ca176f3fee24f873f0fd60010773d67
