Description

A flaw was found in the Linux kernel's MediaTek PCIe driver. When a Peripheral Component Interconnect Express (PCIe) port fails to enable, the associated Interrupt Request (IRQ) domains are not properly released. This resource leak can accumulate over time, potentially leading to a denial of service (DoS) due to resource exhaustion.
