Description Adam Mariš 2016-10-10 14:07:20 UTC 
A flaw was found in the Linux kernel in versions before 4.1 on arm64 platforms allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via vectors involving events that are mishandled during a span of multiple HW PMUs.
