CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-1000380
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in the sound/core/timer.c code due to a race condition that exists in the timing functionality of the ALSA/dev/snd/timer driver when a read and an ioctl system call happens simultaneously. A local attacker can cause uninitialized memory from the kernel heap to be copied to user space and read kernel-space memory.
