| Subject: CVE-2024-58086: drm/v3d: Stop active perfmon if it is being destroyed |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/v3d: Stop active perfmon if it is being destroyed |
| |
| If the active performance monitor (`v3d->active_perfmon`) is being |
| destroyed, stop it first. Currently, the active perfmon is not |
| stopped during destruction, leaving the `v3d->active_perfmon` pointer |
| stale. This can lead to undefined behavior and instability. |
| |
| This patch ensures that the active perfmon is stopped before being |
| destroyed, aligning with the behavior introduced in commit |
| 7d1fd3638ee3 ("drm/v3d: Stop the active perfmon before being destroyed"). |
| |
| The Linux kernel CVE team has assigned CVE-2024-58086 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: |
