CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the mediatek-gen3 PCI driver, where IRQ domains are allocated before successfully fetching the controller's IRQ. This oversight can lead to resource leaks if the IRQ retrieval fails, potentially impacting system stability and performance. Linux distributions utilizing the mediatek-gen3 driver should prioritize this fix to ensure proper resource management and avoid potential operational issues.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: PCI: mediatek-gen3: Prevent leaking IRQ domains when IRQ not found In mtk_pcie_setup_irq(), the IRQ domains are allocated before the controller's IRQ is fetched. If the latter fails, the function directly returns an error, without cleaning up the allocated domains. Hence, reverse the order so that the IRQ domains are allocated after the controller's IRQ is found. This was flagged by Sashiko during a review of "[PATCH v6 0/7] PCI: mediatek-gen3: add power control support".
