CVE-2024-46674

usb: dwc3: st: fix probed platform device ref count on probe error path

State: Published
Severity: 7.8 High
Published: Sep 13, 2024
Updated: Aug 5, 2026
Reserved: Sep 11, 2024

Description

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

usb: dwc3: st: fix probed platform device ref count on probe error path

The probe function never performs any paltform device allocation, thus error path "undo_platform_dev_alloc" is entirely bogus. It drops the reference count from the platform device being probed. If error path is triggered, this will lead to unbalanced device reference counts and premature release of device resources, thus possible use-after-free when releasing remaining devm-managed resources.
