Overview

CVE-2024-56698 is a medium-severity vulnerability. It was published on December 28, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

usb: dwc3: gadget: Fix looping of queued SG entries

The dwc3_request->num_queued_sgs is decremented on completion. If a

partially completed request is handled, then the

dwc3_request->num_queued_sgs no longer reflects the total number of

num_queued_sgs (it would be cleared).

Correctly check the number of request SG entries remained to be prepare

and queued. Failure to do this may cause null pointer dereference when

accessing non-existent SG entry.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
