Overview

What is CVE-2026-46109?

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

usb: ulpi: fix memory leak on ulpi_register() error paths

Commit 01af542392b5 ("usb: ulpi: fix double free in ulpi_register_interface() error path") removed kfree(ulpi) from ulpi_register_interface() to fix a double-free when device_register() fails.

But when ulpi_of_register() or ulpi_read_id() fail before device_register() is called, the ulpi allocation is leaked.

Add kfree(ulpi) on both error paths to properly clean up the allocation.
