| Subject: CVE-2025-21697: drm/v3d: Ensure job pointer is set to NULL after job completion |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/v3d: Ensure job pointer is set to NULL after job completion |
| |
| After a job completes, the corresponding pointer in the device must |
| be set to NULL. Failing to do so triggers a warning when unloading |
| the driver, as it appears the job is still active. To prevent this, |
| assign the job pointer to NULL after completing the job, indicating |
| the job has finished. |
| |
| The Linux kernel CVE team has assigned CVE-2025-21697 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: |
