Affected files ============== The file(s) affected by this issue are: drivers/scsi/zorro7xx.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/ce430cfad6a5385d5b7f7c1dc3fa50f10abfd41b https://git.kernel.org/stable/c/1e0c01319dedf1e63ec5df37ead048e17afd92ba https://git.kernel.org/stable/c/db863ab2baf058ed05c7b723612e3c40c9dd6885 https://git.kernel.org/stable/c/34a47f7ddb4fd1cbd12397aa6f7dad1de08b4050 https://git.kernel.org/stable/c/c5f77b595379b5191316edd365a542f8b1526066 https://git.kernel.org/stable/c/aefd755a96051aa56b198cb7ecd168b22ba384f6 https://git.kernel.org/stable/c/de6aee0978f164d3d0c771ce03e3066a26c371c5 https://git.kernel.org/stable/c/a845c678e094894f38cc9526d212b21933ce44c7 https://git.kernel.org/stable/c/16ed828b872d12ccba8f07bcc446ae89ba662f9c
