CVE-2026-64332 Details
Description
In the Linux kernel, the following vulnerability has been resolved: USB: ulpi: fix memory leak on registration failure The allocated device name is never freed on early ULPI device registration failures. Fix this by initialising the device structure earlier and releasing the initial reference whenever registration fails.
A memory leak vulnerability has been identified in the USB ULPI (Unified Layered Protocol Interface) driver of the Linux kernel. This issue arises during the device registration process, where the allocated device name is not properly freed if an early registration failure occurs. The vulnerability is present in the Linux kernel stable tree.
The vulnerability has been addressed by modifying the ULPI registration process to initialize the device structure earlier and ensure that the initial reference is released whenever a registration failure occurs. Users can apply the latest patches available in the Linux kernel stable tree to mitigate this vulnerability.
