Overview

Affected versions of this package are vulnerable to Deadlock in the cdc_ncm_send process. An attacker can cause the device to deadlock and halt network transmission by triggering a USB bus suspend or disconnect while the network interface is active and attempting to send traffic. This results in a persistent loss of the virtual network connection and can stall egress on other network interfaces as well. This is only exploitable if the USB host suspends the bus or disconnects while the device has active traffic to send.
