CVE-2025-68656
6.8 · MEDIUMOverview
CVE-2025-68656 is a medium-severity vulnerability affecting espressif usb_host_hid_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 HID (Human Interface Device) Driver allows access to HID devices. Prior to 1.1.0, usb_class_request_get_descriptor() frees and reallocates hid_device->ctrl_xfer when an oversized descriptor is requested but continues to use the stale local pointer, leading to an immediate use-after-free when processing attacker-controlled Report Descriptor lengths. This vulnerability is fixed in 1.1.0.
Remediation
Check the references section for vendor advisories and patches from espressif. Update usb_host_hid_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.
