Summary
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: qcom: clear opened when stream enable fails On enable, subs->opened is set before the service_interval is validated; an invalid interval jumps to the response label without clearing it, so the substream is wedged at -EBUSY until a disable or disconnect.
An attacker, by providing an invalid service interval during stream enablement, can cause the audio substream to become unresponsive. This can lead to a Denial of Service (DoS) for the affected audio device, requiring a disable or disconnect to restore functionality.
