Affected files ============== The file(s) affected by this issue are: drivers/iio/light/bh1780.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/1eb3af4f59e09323788860a9155e9766b12891e5 https://git.kernel.org/stable/c/424bf90e87134effe4bd932608a15286493b11ab https://git.kernel.org/stable/c/fc77e0a5600e620a2ae51ec78933162fb217b20b https://git.kernel.org/stable/c/aae572ddc28578af476cce7da3faec0395ef0bf0 https://git.kernel.org/stable/c/33661bfc85c14836bfef4425a74b0ca2df4bb5ad https://git.kernel.org/stable/c/dd72e6c3cdea05cad24e99710939086f7a113fb5
