## Overview

In the Linux kernel, the following vulnerability has been resolved:

tracing/osnoise: Call synchronize_rcu() when unregistering

This ensures that any RCU readers traversing the instance list
have finished, before releasing the reference on the tracer that
the instance points to.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
