| Subject: CVE-2023-53037: scsi: mpi3mr: Bad drive in topology results kernel crash |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: mpi3mr: Bad drive in topology results kernel crash |
| |
| When the SAS Transport Layer support is enabled and a device exposed to |
| the OS by the driver fails INQUIRY commands, the driver frees up the memory |
| allocated for an internal HBA port data structure. However, in some places, |
| the reference to the freed memory is not cleared. When the firmware sends |
| the Device Info change event for the same device again, the freed memory is |
| accessed and that leads to memory corruption and OS crash. |
| |
| The Linux kernel CVE team has assigned CVE-2023-53037 to this issue. |

| 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/1f822ae8fb2a20fffa71e9bfa9b203c03d72d3ba |
