| Subject: CVE-2024-50003: drm/amd/display: Fix system hang while resume with TBT monitor |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Fix system hang while resume with TBT monitor |
| |
| [Why] |
| Connected with a Thunderbolt monitor and do the suspend and the system |
| may hang while resume. |
| |
| The TBT monitor HPD will be triggered during the resume procedure |
| and call the drm_client_modeset_probe() while |
| struct drm_connector connector->dev->master is NULL. |
| |
| It will mess up the pipe topology after resume. |
| |
| [How] |
| Skip the TBT monitor HPD during the resume procedure because we |
| currently will probe the connectors after resume by default. |
| |

| 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: |
