| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.11.5
Description
The issue is related to a data race in the ALSA /dev/snd/timer driver of the Linux kernel, which can lead to the disclosure of information. This can occur when a read and an ioctl happen simultaneously, potentially allowing a local attacker to access confidential information by exploiting access rights to sound devices. The vulnerable component is located in sound/core/timer.c.
Recommendations
For Linux kernel versions prior to 4.11.5, update to version 4.11.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the sound devices to minimize the risk of exploitation.
