Espressif ESP-IDF USB Host HID (Human Interface Device) Driver Descriptor Use-After-Free Vulnerability
Source: CVE Program / CVE List V5
Vulnerability 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.
