CVE-2025-68656: Espressif USB Host Hid Driver

Medium severity, CVSS 6.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Espressif USB Host Hid Driver: before 1.1.0 (fixed in 1.1.0)
