NVD Description

Note: Versions mentioned in the description apply only to the upstream realtime-kernel package and not the realtime-kernel package as distributed by RHEL.

sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.
