Affected files ============== The file(s) affected by this issue are: drivers/clk/ti/clk-dra7-atl.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/27abe45df1dc394c184688d816cbbf2f194d4c6a https://git.kernel.org/stable/c/d84f77ef7d57658d7346f8c4797a570aa5e35fa6 https://git.kernel.org/stable/c/25fe7b0d596b343e7a5504ba11767115fff8494f https://git.kernel.org/stable/c/fc39ebf85d0349366b807fe2be848041c8523f03 https://git.kernel.org/stable/c/6d01017247eee3fba399f601b0bcb38e4fb88a72 https://git.kernel.org/stable/c/3441076f83aace85f5d6ccd9ffb301ac6b874776 https://git.kernel.org/stable/c/a9f69663ad571cbd7814dde38e3fcb4876341ed6 https://git.kernel.org/stable/c/c01ae99a4e3a0cdf70f7cd758a60a2243eac562c https://git.kernel.org/stable/c/9c59a01caba26ec06fefd6ca1f22d5fd1de57d63
