Detailsinfo

A vulnerability was found in Linux Kernel up to 6.10.7. It has been rated as critical. Affected by this issue is the function undo_platform_dev_alloc of the component dwc3. The manipulation with an unknown input leads to a reference count vulnerability. Using CWE to declare the problem leads to CWE-911. The product uses a reference count to manage a resource, but it does not update or incorrectly updates the reference count. Impacted is availability. CVE summarizes:

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.

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2024-46674 since 09/11/2024. There are known technical details, but no exploit is available.
