Description
A flaw was found in the Linux kernel's mt76 Wi-Fi driver. This vulnerability, a memory leak, occurs when the device is destroyed during module unload. Specifically, the mt76_dma_cleanup routine fails to properly destroy the page_pool associated with all MT76 receive queues, leading to unreleased memory. Over time, this can lead to system instability or a denial of service (DoS) due to resource exhaustion.
