Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.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/fdb880a7d575efe8b5c7b5b819b96d9251a3937f https://git.kernel.org/stable/c/261d7c7610b4b2f476382c88a2d1ae0cc5e07add https://git.kernel.org/stable/c/ba04715ee672c336272be3ceb43bda9ffc33eb75 https://git.kernel.org/stable/c/0d10db8e94fcb23a799789aaa696b4d8f937e207
