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.
Clear subs->opened on the enable error path.

Clear subs->opened on the enable error path.
A flaw was found in the Linux kernel's ALSA USB audio driver for QCOM devices. 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.
