A fix is available — apply it.

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

most: core: fix resource leak in most_register_interface error paths

The function most_register_interface() did not correctly release resources if it failed early (before registering the device). In these cases, it returned an error code immediately, leaking the memory allocated for the interface.

Fix this by initializing the device early via device_initialize() and calling put_device() on all error paths.

The most_register_interface() is expected to call put_device() on error which frees the resources allocated in the caller. The put_device() either calls release_mdev() or dim2_release(), depending on the caller.

Switch to using device_add() instead of device_register() to handle the split initialization.
