Affected files ============== The file(s) affected by this issue are: drivers/iio/proximity/hx9023s.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/451ec5e67444f8460f9706a1bde146b5bbc86ce6 https://git.kernel.org/stable/c/ad9da7d39cecd3e92f54149ea0ebca390f33fe69 https://git.kernel.org/stable/c/739fdfe65678d8e5dcf59496c56b32ab3ba3dbaa https://git.kernel.org/stable/c/a318cfc0853706f1d6ce682dba660bc455d674ef
