CVE-2022-36063
No affected components available
Azure RTOS USBx is a USB host, device, and on-the-go (OTG) embedded stack, fully integrated with Azure RTOS ThreadX and available for all Azure RTOS ThreadX–supported processors. Azure RTOS USBX implementation of host support for USB CDC ECM includes an integer underflow and a buffer overflow in the _ux_host_class_cdc_ecm_mac_address_get function which may be potentially exploited to achieve remote code execution or denial of service. Setting mac address string descriptor length to a 0 or 1 allows an attacker to introduce an integer underflow followed (string_length) by a buffer overflow of the cdc_ecm -> ux_host_class_cdc_ecm_node_id array. This may allow one to redirect the code execution flow or introduce a denial of service. The fix has been included in USBX release 6.1.12. Improved mac address string descriptor length validation to check for unexpectedly small values may be used as a workaround.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists.
