Vigil@nce - Linux kernel: information disclosure via snd_timer_user_params
May 2016 by Vigil@nce
SYNTHESIS OF THE VULNERABILITY
A local attacker can read a memory fragment of
snd_timer_user_params() on the Linux kernel, in order to obtain
sensitive information.
Impacted products: Linux.
Severity: 1/4.
Creation date: 09/05/2016.
DESCRIPTION OF THE VULNERABILITY
The Linux kernel implements a low level sound driver.
However, the snd_timer_user_params() function of the
sound/core/timer.c file does not initialize a memory area before
returning it to the user.
A local attacker can therefore read a memory fragment of
snd_timer_user_params() on the Linux kernel, in order to obtain
sensitive information.
