Background

The Kernel is a critical component of the Linux operating system that manages system resources and provides an interface for applications to interact with the hardware. It is responsible for tasks such as process management, memory management, and device drivers. The SUNRPC (Simple Unified Network RPC) subsystem within the Kernel facilitates remote procedure calls (RPC) over a network.

The svc_deferred_event trace class is a feature in the SUNRPC subsystem that allows deferred events to be traced. However, a vulnerability has been discovered in this trace class, which could potentially be exploited by attackers.
