CVE-2024-57926

CVE-2024-57926 is a Linux kernel vulnerability affecting the Mediatek DRM path. The issue arises in the shutdown path where private->all_drm_private[i]->drm may be accessed after a failed mtk_drm_bind, causing a use-after-free detected by KASAN in drm_atomic_helper_shutdown. The root cause ...

CVE-2024-57926 drm/mediatek: Set private->all_drm_private[i]->drm to NULL if mtk_drm_bind returns err

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Set private-alldrmprivatei-drm to NULL if mtkdrmbind returns err The pointer need to be set to NULL, otherwise KASAN complains about use-after-free. Because in mtkdrmbind, all private's drm are set as follows...
