CVE-2025-68249

In the Linux kernel, the following vulnerability has been resolved: most: usb: hdm_probe: Fix calling put_device() before device initialization The early error path in hdm_probe() can jump to err_free_mdev before &mdev->dev has been initialized with device_initialize(). Calling put_device(&mdev->dev) there triggers a device core WARN and ends up invoking kref_put(&kobj->kref, kobject_release) on an uninitialized kobject. In this path the private struct was only kmalloc'ed and the intended release is effectively kfree(mdev) anyway, so free it directly instead of calling put_device() on an uninitialized device. This removes the WARNING and fixes the pre-initialization error path.
