Affected files ============== The file(s) affected by this issue are: net/bluetooth/iso.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/ba25efe15e8fd909884e113a86c6ccd07d88256e https://git.kernel.org/stable/c/927ef409f713929dea2b9a5ed5bb65e712be0050 https://git.kernel.org/stable/c/f4da3ee15de9944482382181329bb6d7335ca003
