Affected files ============== The file(s) affected by this issue are: drivers/hsi/controllers/omap_ssi_core.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/20fbaff6699ea5553c67550e867d6f90b7085447 https://git.kernel.org/stable/c/18e199a5541aad6dc5cf51bc3f712247b2d17894 https://git.kernel.org/stable/c/e8a218c17d7c5c42d5609ef92d339b47f3d11d02 https://git.kernel.org/stable/c/aa9c0598b10960ad1198044da1e277a89b4e3af6 https://git.kernel.org/stable/c/962f22e7f7698f7718d95bd9b63e41fb8cca01a9 https://git.kernel.org/stable/c/691f23a8475f04c988f7e98066b084e996b40fa0 https://git.kernel.org/stable/c/e25f56f8bdf66126a54b5a88bc021c82bfb50b75 https://git.kernel.org/stable/c/0eff9ef67d91e350d2047c3e13b6c3b7d0c90bf4 https://git.kernel.org/stable/c/9a2ea132df860177b33c9fd421b26c4e9a0a9396
