Johan Hovold 5d1b71226d ALSA: usb-audio: fix sync-ep altsetting sanity check ... The altsetting sanity check in set_sync_ep_implicit_fb_quirk() was checking for there to be at least one altsetting but then went on to access the second one, which may not exist. This could lead to random slab data being used to initialise the sync endpoint in snd_usb_add_endpoint(). Fixes: c75a8a7ae5 ("ALSA: snd-usb: add support for implicit feedback") Fixes: ca10a7ebdf ("ALSA: usb-audio: FT C400 sync playback EP to capture EP") Fixes: 5e35dc0338 ("ALSA: usb-audio: add implicit fb quirk for Behringer UFX1204") Fixes: 17f08b0d9a ("ALSA: usb-audio: add implicit fb quirk for Axe-Fx II") Fixes: 103e962564 ("ALSA: usb-audio: simplify set_sync_ep_implicit_fb_quirk") Cc: stable <stable@vger.kernel.org> # 3.5 Signed-off-by: Johan Hovold <johan@kernel.org> Link: https://lore.kernel.org/r/20200114083953.1106-1-johan@kernel.org Signed-off-by: Takashi Iwai <tiwai@suse.de>		2020-01-14 09:42:01 +01:00
