Описание
sound/core/timer.c in the Linux kernel before 4.4.1 employs a locking approach that does not consider slave timer instances, which allows local users to cause a denial of service (race condition, use-after-free, and system crash) via a crafted ioctl call.
Отчет
This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6. This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates.
