Description OSIDB Bzimport 2026-06-24 18:09:05 UTC 
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.
