| Subject: CVE-2022-48824: scsi: myrs: Fix crash in error case |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: myrs: Fix crash in error case |
| |
| In myrs_detect(), cs->disable_intr is NULL when privdata->hw_init() fails |
| with non-zero. In this case, myrs_cleanup(cs) will call a NULL ptr and |
| crash the kernel. |
| |
| [ 1.105606] myrs 0000:00:03.0: Unknown Initialization Error 5A |
| [ 1.105872] myrs 0000:00:03.0: Failed to initialize Controller |
| [ 1.106082] BUG: kernel NULL pointer dereference, address: 0000000000000000 |

| 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: |
