CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-35927 – drm: Check output polling initialized before disabling
https://notcve.org/view.php?id=CVE-2024-35927
In the Linux kernel, the following vulnerability has been resolved: drm: Check output polling initialized before disabling In drm_kms_helper_poll_disable() check if output polling support is initialized before disabling polling. If not flag this as a warning. Additionally in drm_mode_config_helper_suspend() and drm_mode_config_helper_resume() calls, that re the callers of these functions, avoid invoking them if polling is not initialized. For drivers like hyperv-drm, that do not initialize connector polling, if suspend is called without this check, it leads to suspend failure with following stack [ 770.719392] Freezing remaining freezable tasks ...
