Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.7

Description The issue is related to the snd timer user params function in the sound/core/timer.c file of the Linux kernel. This function does not properly initialize a certain data structure, allowing local users to obtain sensitive information from kernel stack memory. This can be achieved through crafted use of the ALSA timer interface.
