| Subject: CVE-2021-47565: scsi: mpt3sas: Fix kernel panic during drive powercycle test |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: mpt3sas: Fix kernel panic during drive powercycle test |
| |
| While looping over shost's sdev list it is possible that one |
| of the drives is getting removed and its sas_target object is |
| freed but its sdev object remains intact. |
| |
| Consequently, a kernel panic can occur while the driver is trying to access |
| the sas_address field of sas_target object without also checking the |
| sas_target object for NULL. |
| |
| The Linux kernel CVE team has assigned CVE-2021-47565 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: |
