A race condition in perfeventopen() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc.

Other sources

A race condition was found the Linux kernel in perfeventopen() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc.

A use-after-free flaw was found in the Linux kernel’s performance events functionality. A user triggers a race condition in setting up performance monitoring between the leading PERFTYPETRACEPOINT and sub PERFEVENTHARDWARE plus the PERFEVENTSOFTWARE using the perfeventopen() function with these three types. This flaw allows a local user to crash the system.
