Affected files ============== The file(s) affected by this issue are: sound/soc/mediatek/common/mtk-soundcard-driver.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/3e40722d55805584dc04d8594d912820cafb2432 https://git.kernel.org/stable/c/beed115c2ce78f990222a29abed042582df4e87c
