Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/broadcom/brcm80211/brcmfmac/pcie.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/d0ab87f8dcdfe72dc1d763be3392c1fc51a1ace2 https://git.kernel.org/stable/c/f3820ddaf4f3ac80c7401ccc6a42e663c9317f31 https://git.kernel.org/stable/c/a88337a06966f2d733ad9a97714b874469133f14 https://git.kernel.org/stable/c/4e0b507597e1a86e9b4c056ab274c427223cf8ea https://git.kernel.org/stable/c/0347bdfdb1529994ac3a4cb425087c477a74eb2c https://git.kernel.org/stable/c/5e90f0f3ead014867dade7a22f93958119f5efab
