Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/intel/iwlwifi/mei/main.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/a4034f1cc8a422cefc519290d8e6cfb7ff773586 https://git.kernel.org/stable/c/b90ebae632318dc2e5cd4ac96e454ec50f705579 https://git.kernel.org/stable/c/9c6bea89a16815688a5240dd4a74c922a92fcdc3 https://git.kernel.org/stable/c/242125bbf19a2974d22f3d5025c9c14c0a4aea58 https://git.kernel.org/stable/c/f7f770d12e6e928006f89a59291074e5fea82886 https://git.kernel.org/stable/c/7d8cc301bcba233f31b589a45f4c1c97f2bb90d6
