CVE-2025-68656: Espressif ESP-IDF USB Host HID (Human Interface Device) Driver allows access to HID devices
CVE-2025-68656 is a medium-severity flaw (CVSS 6.8) affecting usb host hid driver. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
