Executive Summary

This vulnerability is a resource leak in the Linux kernel's crypto module for hisilicon/hpre. Specifically, in the hpre_remove() function, if the disable operation of qm sriov fails, the function should continue executing the logic to release allocated resources instead of returning immediately. Failing to do so causes resource leakage.

Impact Analysis

The resource leak caused by this vulnerability can lead to inefficient use of system resources, potentially degrading system performance or causing instability over time if resources are not properly released.
