| Subject: CVE-2024-27062: nouveau: lock the client object tree. |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nouveau: lock the client object tree. |
| |
| It appears the client object tree has no locking unless I've missed |
| something else. Fix races around adding/removing client objects, |
| mostly vram bar mappings. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
