CVE-2026-53104 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: Fix memory leak destroying device All MT76 rx queues have an associated page_pool even if the queue is not associated to a NAPI (e.g. WED RRO queues with WED enabled). Destroy the page_pool running mt76_dma_cleanup routine during module unload. Moreover returns pages to the page pool if WED is not enabled for WED RRO queues.
A memory leak vulnerability has been identified in the Linux kernel's MT76 Wi-Fi driver. This issue arises because all MT76 receive queues are linked to a page pool, even those not associated with a NAPI, such as WED RRO queues with WED enabled. During module unload, the page pool is not properly destroyed, leading to a memory leak. The vulnerability has been addressed by ensuring the page pool is cleaned up and that pages are returned to the pool when WED is not active on WED RRO queues.
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
