| Subject: CVE-2024-36924: scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up() |
| |
| lpfc_worker_wake_up() calls the lpfc_work_done() routine, which takes the |
| hbalock. Thus, lpfc_worker_wake_up() should not be called while holding the |
| hbalock to avoid potential deadlock. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36924 to this issue. |
| |
| |
| Affected and fixed versions |

| 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: |
