Affected files ============== The file(s) affected by this issue are: arch/xtensa/kernel/time.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/3e5eb904d9ba657308fc75a5de434b0e58dcb8d7 https://git.kernel.org/stable/c/7de4502af68f4f3932f450157f5483eb7b33cb74 https://git.kernel.org/stable/c/f1eaf4ba5372ad111f687a80c67e270708e14c23 https://git.kernel.org/stable/c/e5234a9d64a976abd134a14710dcd5188158a7c5 https://git.kernel.org/stable/c/af0ff2da01521144bc11194f4c26485d7c9cee73 https://git.kernel.org/stable/c/0dcc1dd8a5dd9240639f1051dfaa2dffc9fbbde5 https://git.kernel.org/stable/c/0e403a383c14b63c86bd9df085b7e573e9caee64 https://git.kernel.org/stable/c/a0117dc956429f2ede17b323046e1968d1849150
