Affected files ============== The file(s) affected by this issue are: drivers/memory/tegra/tegra124-emc.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/a85967331144fde9300be38bb44d2558eb6b742e https://git.kernel.org/stable/c/db0ae80865b515cc0b705c85877ec00f7eebe9fe https://git.kernel.org/stable/c/2369b1831161356e1bcb51385d3e532dc4fe2771 https://git.kernel.org/stable/c/7e19e72f306484996c52ff96cc92f69b78ed5435 https://git.kernel.org/stable/c/05f138fc7e27ee8e7a83ccf966c3fa26cda44dda https://git.kernel.org/stable/c/1793249c067a4b28e1aba0ad0e4d73aa9f9e165a https://git.kernel.org/stable/c/1ebbbef47d11cc90219c081492ccf995aaa3e9b3 https://git.kernel.org/stable/c/9597ab9a8296ab337e6820f8a717ff621078b632
