| Subject: CVE-2024-50183: scsi: lpfc: Ensure DA_ID handling completion before deleting an NPIV instance |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: lpfc: Ensure DA_ID handling completion before deleting an NPIV instance |
| |
| Deleting an NPIV instance requires all fabric ndlps to be released before |
| an NPIV's resources can be torn down. Failure to release fabric ndlps |
| beforehand opens kref imbalance race conditions. Fix by forcing the DA_ID |
| to complete synchronously with usage of wait_queue. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50183 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: |
