The vulnerability allows a local user to perform a denial of service (DoS) attack or escalate privileges on the system.

The vulnerability exists due to improper management of internal resources in POSIX CPU timers when handling death of a process. A local user can crash the kernel or execute arbitrary code.

Install updates from vendor's website.
