Affected files ============== The file(s) affected by this issue are: drivers/phy/marvell/phy-mvebu-a3700-comphy.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/976df695f579bbb2914114b4e9974fe4ed1eb813 https://git.kernel.org/stable/c/610f175d2e16fb2436ba7974b990563002c20d07 https://git.kernel.org/stable/c/40406dfbc060503d2e0a9e637e98493c54997b3d https://git.kernel.org/stable/c/e4308bc22b9d46cf33165c9dfaeebcf29cd56f04
