      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm: fix race between partial drm_dev_register() failure and ioctl\n\nIf drm_dev_register() fails after registering a minor (e.g. render minor\nregistered, primary minor fails), userspace could have opened the first\nminor and entered a drm_dev_enter() critical section. Since the\nunplugged flag was never set, the ioctl proceeds while the error path\ntears down device resources.\n\nFix this by introducing drm_dev_synchronize_unplug(), which sets the\nunplugged flag and waits for the SRCU barrier, ensuring all in-flight\ndrm_dev_enter() critical sections complete before cleanup proceeds; call\nit on the error path of drm_dev_register().",
