CVE-2026-53104

Estado: AnalizadaMedia (5.5)—

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.
