• EPSS: 0.2% probability of exploitation in the next 30 days

Description

Espressif ESP-IDF USB Host HID (Human Interface Device) Driver allows access to HID devices. Prior to 1.1.0, calls to hid_host_device_close() can free the same usb_transfer_t twice. The USB event callback and user code share the hid_iface_t state without locking, so both can tear down a READY interface simultaneously, corrupting heap metadata inside the ESP USB host stack. This vulnerability is fixed in 1.1.0.

Affected products

• espressif esp-usb: before 1.1.0 — fixed in 1.1.0

How to fix

Upgrade to a fixed version: espressif esp-usb 1.1.0. Check the vendor advisory for mitigations.
