CVE-2025-68249: most: usb: hdm_probe: Fix calling put_device() before device initialization

Published Dec 16, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved:

most: usb: hdmprobe: Fix calling putdevice() before device initialization

The early error path in hdmprobe() can jump to errfreemdev before &mdev->dev has been initialized with deviceinitialize(). Calling putdevice(&mdev->dev) there triggers a device core WARN and ends up invoking krefput(&kobj->kref, kobjectrelease) 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 putdevice() on an uninitialized device.

This removes the WARNING and fixes the pre-initialization error path.
