Affected files ============== The file(s) affected by this issue are: drivers/soc/ti/pm33xx.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/08310f810975c8c9e17c6ffb99fdb76a84e8adb7 https://git.kernel.org/stable/c/6a50350033e0e0854acf59a8413913b4de04bd7d https://git.kernel.org/stable/c/6dbcc493a18dd60947c2168a39df0ec2fe7b5110 https://git.kernel.org/stable/c/e6c6b40c9bf49ce9b5493b146bfeb96359937cfa https://git.kernel.org/stable/c/65305e8c0009a1933679dad5c8196060a10f3c8b https://git.kernel.org/stable/c/8f3c307b580a4a6425896007325bddefc36e8d91
