CVE-2025-68622
6.8 · MEDIUMOverview
CVE-2025-68622 is a medium-severity vulnerability affecting espressif usb_host_uvc_class_driver. It was published on January 12, 2026 and has a CVSS 3.1 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Espressif ESP-IDF USB Host UVC Class Driver allows video streaming from USB cameras. Prior to 2.4.0, a vulnerability in the esp-usb UVC host implementation allows a malicious USB Video Class (UVC) device to trigger a stack buffer overflow during configuration-descriptor parsing. When UVC configuration-descriptor printing is enabled, the host prints detailed descriptor information provided by the connected USB device. A specially crafted UVC descriptor may advertise an excessively large length. Because this value is not validated before being copied into a fixed-size stack buffer, an attacker can overflow the buffer and corrupt memory. This vulnerability is fixed in 2.4.0.
Remediation
Check the references section for vendor advisories and patches from espressif. Update usb_host_uvc_class_driver to the latest patched version. 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.
