CVE-2025-68657: Espressif USB Host Hid Driver

Medium severity, CVSS 6.4. 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, 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 USB Host Hid Driver: before 1.1.0 (fixed in 1.1.0)
