Hello, In function snd_timer_user_ccallback() of file sound/core/timer.c, the stack object “r1” has a total size of 32 bytes. Its field “event” and “val” both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.

Maybe we can fold all three similar bugs in sound/core/timer.c into the existing CVE-2016-4569? In my sound.git tree, cec8f96e49d9be372fdb0c3836dcf31ec71e457e ALSA: timer: Fix leak in SNDRV_TIMER_IOCTL_PARAMS 9a47e9cff994f37f7f0dbd9ae23740d0f64f9fe6 ALSA: timer: Fix leak in events via snd_timer_user_ccallback e4ec8cc8039a7063e24204299b462bd1383184a5 ALSA: timer: Fix leak in events via snd_timer_user_tinterrupt BTW, at the next time, *please* put the upstream maintainer into the loop...
