CVE-2023-53388

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/mediatek: Clean dangling pointer on bind error path<br /> <br /> mtk_drm_bind() can fail, in which case drm_dev_put() is called,<br /> destroying the drm_device object. However a pointer to it was still<br /> being held in the private object, and that pointer would be passed along<br /> to DRM in mtk_drm_sys_prepare() if a suspend were triggered at that<br /> point, resulting in a panic. Clean the pointer when destroying the<br /> object in the error path to prevent this from happening.
