Affected files ============== The file(s) affected by this issue are: drivers/i2c/i2c-dev.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/2f345bb14ad4744950499ff222e2899209297afa https://git.kernel.org/stable/c/c74d77a2d07744147d734138acd6ce9dba715e5d https://git.kernel.org/stable/c/993eb48fa199b5f476df8204e652eff63dd19361
