| Subject: CVE-2024-45007: char: xillybus: Don't destroy workqueue from work item running on it |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| char: xillybus: Don't destroy workqueue from work item running on it |
| |
| Triggered by a kref decrement, destroy_workqueue() may be called from |
| within a work item for destroying its own workqueue. This illegal |
| situation is averted by adding a module-global workqueue for exclusive |
| use of the offending work item. Other work items continue to be queued |
| on per-device workqueues to ensure performance. |
| |
| The Linux kernel CVE team has assigned CVE-2024-45007 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: |
