Affected files ============== The file(s) affected by this issue are: drivers/scsi/mpt3sas/mpt3sas_scsih.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/b8fc9e91b931215110ba824d1a2983c5f60b6f82 https://git.kernel.org/stable/c/d4959d09b76eb7a4146f5133962b88d3bddb63d6 https://git.kernel.org/stable/c/82efb917eeb27454dc4c6fe26432fc8f6c75bc16 https://git.kernel.org/stable/c/5682c94644fde72f72bded6580c38189ffc856b5 https://git.kernel.org/stable/c/ea10a652ad2ae2cf3eced6f632a5c98f26727057 https://git.kernel.org/stable/c/6229fa494a5949be209bc73afbc5d0a749c2e3c7 https://git.kernel.org/stable/c/41acb064c4e013808bc7d5fc1b506fa449425b0b https://git.kernel.org/stable/c/991df3dd5144f2e6b1c38b8d20ed3d4d21e20b34
