| Subject: CVE-2023-53124: scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add() |
| |
| Port is allocated by sas_port_alloc_num() and rphy is allocated by either |
| sas_end_device_alloc() or sas_expander_alloc(), all of which may return |
| NULL. So we need to check the rphy to avoid possible NULL pointer access. |
| |
| If sas_rphy_add() returned with failure, rphy is set to NULL. We would |
| access the rphy in the following lines which would also result NULL pointer |
| access. |
| |
| The Linux kernel CVE team has assigned CVE-2023-53124 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: |
