| Subject: CVE-2024-42261: drm/v3d: Validate passed in drm syncobj handles in the timestamp extension |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/v3d: Validate passed in drm syncobj handles in the timestamp extension |
| |
| If userspace provides an unknown or invalid handle anywhere in the handle |
| array the rest of the driver will not handle that well. |
| |
| Fix it by checking handle was looked up successfully or otherwise fail the |
| extension by jumping into the existing unwind. |
| |
| (cherry picked from commit 8d1276d1b8f738c3afe1457d4dff5cc66fc848a3) |

| 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: |
| https://git.kernel.org/stable/c/5c56f104edd02a537e9327dc543574e55713e1d7 |
