Affected files ============== The file(s) affected by this issue are: arch/arm/mach-omap2/prm3xxx.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/c9ec7993d00250a394d367c8a19fcfe8211c258b https://git.kernel.org/stable/c/c4f92af7fc8cecb8eb426ad187e39c7bcc6679c7 https://git.kernel.org/stable/c/d294d60dc68550fee0fbbe8a638d798dcd40b2c5 https://git.kernel.org/stable/c/1bf747824a8ca4008879fd7d2ce6b03d7b428858 https://git.kernel.org/stable/c/e5ab8a4967d68a8e9f8f4559d144207d085a8c02 https://git.kernel.org/stable/c/c652e0f51665f3fa575449909bbd9d7b45dfab1c https://git.kernel.org/stable/c/942228fbf5d4901112178b93d41225be7c0dd9de
