What is CVE-2023-53375?

A memory leak has been identified in the Linux kernel's tracing functionality. When a tracing instance is removed, error messages intended for that instance are not properly freed, leading to unreferenced memory. This issue can potentially degrade system performance and stability as memory resources become exhausted over time. Proper management of error logs within tracing instances is crucial for maintaining system health and preventing resource leaks.
