  "details": "In the Linux kernel, the following vulnerability has been resolved:  ALSA: usb-audio: Clamp frame size in implicit-feedback mode  snd_usb_handle_sync_urb() scales received sync packet sizes by the sender's stride and stores the result directly in out_packet-\u003epacket_size[i]. If a connected USB device sends an oversized sync packet, this frame count can exceed ep-\u003emaxframesize.  The un-clamped frame count then propagates to the playback endpoint queue, potentially driving packet transfers beyond the endpoint's hardware frame limits.  Cap the calculated frame count against ep-\u003emaxframesize in snd_usb_handle_sync_urb() to prevent oversized packets from entering the playback queue.",
