Affected files ============== The file(s) affected by this issue are: drivers/infiniband/core/cm.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/b0cab8b517aeaf2592c3479294f934209c41a26f https://git.kernel.org/stable/c/889000874c1204e47c7f2a4945db262a47e7efc9 https://git.kernel.org/stable/c/2febf09a8a8ae4accf908f043f1bab1421056568 https://git.kernel.org/stable/c/2990f223ffa7bb25422956b9f79f9176a5b38346
