Executive Summary

This vulnerability is a resource leak in the Linux kernel's CIFS implementation. Specifically, when the function cifs_copy_file_range() is used on a file involved in swap operations, it fails to free a resource called xid before returning an error (-EOPNOTSUPP). This leads to a xid leak, meaning that the resource is not properly released.

Impact Analysis

The xid leak caused by this vulnerability can lead to resource exhaustion in the kernel, potentially degrading system performance or causing instability over time if the leaked resources accumulate.
