CVE-2017-1000380: Infoleak
First published: Sat Jun 17 2017(Updated: )
A information leak was found in /dev/snd/timer driver which was prone to a data race, leading to uninitialized memory from the kernel heap being copied to user space. A local user with access to /dev/snd/timer could use this flaw to read kernel space memory of other users.
