      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Clamp frame size in implicit-feedback mode\n\nsnd_usb_handle_sync_urb() scales received sync packet sizes by the sender's\nstride and stores the result directly in out_packet->packet_size[i]. If a\nconnected USB device sends an oversized sync packet, this frame count can\nexceed ep->maxframesize.\n\nThe un-clamped frame count then propagates to the playback endpoint queue,\npotentially driving packet transfers beyond the endpoint's hardware frame\nlimits.\n\nCap the calculated frame count against ep->maxframesize in\nsnd_usb_handle_sync_urb() to prevent oversized packets from entering the\nplayback queue.",
