A flaw was found in the Linux kernel's IP Accelerator (IPA) network driver. Specifically, the ipa_start_xmit() function incorrectly manages the transmit (TX) queue during a device's runtime resume process. This can lead to the TX queue stopping permanently because the mechanism intended to restart it is consumed prematurely. Consequently, the cellular data path can become unresponsive, resulting in a Denial of Service (DoS) for network communication.
