Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A resource leak exists in the hpre remove() function within the hisilicon/hpre crypto module. Specifically, when the disable operation of qm sriov fails, resources are not properly released, leading to a resource leak. This occurs because the function returns directly instead of continuing to release allocated resources.
