Affected files ============== The file(s) affected by this issue are: drivers/ata/pata_octeon_cf.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/7bd85c5ba1687daf54e3b6907673c3604b1e75cf https://git.kernel.org/stable/c/a4d3e5f1d7d4f8b5e3834fec0f057a762c55806b https://git.kernel.org/stable/c/8d8ad067b90f231b8fdb14acee673ca4012f6045 https://git.kernel.org/stable/c/d5a1e7f33c88780b279835d63665d7e38ccb671f https://git.kernel.org/stable/c/19cb3ece14547cb1ca2021798aaf49a3f82643d1 https://git.kernel.org/stable/c/888312dc297a8a103f6371ef668c7e04f57a7679 https://git.kernel.org/stable/c/c9782e1b21bee4b783a64b2a91e7e71406c21a21 https://git.kernel.org/stable/c/fb2cb409b504bb3a69e65a17f3120328c8e50219 https://git.kernel.org/stable/c/10d6bdf532902be1d8aa5900b3c03c5671612aa2
