In the Linux kernel, the following vulnerability has been resolved: drm/tests: helpers: Avoid a driver uaf when using __drm_kunit_helper_alloc_drm_device() the driver may be dereferenced by device-managed resources up until the device is freed, which is typically later than the kunit-managed resource code frees it. Fix this by simply make the driver device-managed as well. In short, the sequence leading to the UAF is as follows: INIT: Code allocates a struct device as a kunit-managed resource. Code allocates a drm driver as a kunit-managed resource. Code allocates a drm device as a device-mana
