FKIE_CVE-2025-68656

Vulnerability from fkie_nvd - Published: 2026-01-12 18:15 - Updated: 2026-06-17 09:59
Severity
6.8 (Medium) - CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.
