Affected files ============== The file(s) affected by this issue are: drivers/gpio/gpio-grgpio.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/53ff0caa6ad57372d426b4f48fc0f66df43a731f https://git.kernel.org/stable/c/4733f68e59bb7b9e3d395699abb18366954b9ba7 https://git.kernel.org/stable/c/ad4dfa7ea7f5f7e9a3c78627cfc749bc7005ca7a https://git.kernel.org/stable/c/09adf8792b61c09ae543972a1ece1884ef773848 https://git.kernel.org/stable/c/8d2ca6ac3711a4f4015d26b7cc84f325ac608edb https://git.kernel.org/stable/c/db2fc255fcf41f536ac8666409849e11659af88d https://git.kernel.org/stable/c/050b23d081da0f29474de043e9538c1f7a351b3b
