Executive Summary

This vulnerability is a resource leak in the Linux kernel's fsl_pamu_probe() function. When the create_csd() function fails, fsl_pamu_probe() returns immediately without releasing allocated IRQs and memory, causing those resources to remain unreleased. The fix involves ensuring that the code jumps to an error handling section to properly release these resources if create_csd() fails.

Impact Analysis

The impact of this vulnerability is a resource leak, which can lead to exhaustion of IRQs and memory resources in the system. Over time, this may degrade system stability or performance, potentially causing crashes or failures due to resource depletion.
