Can you explain this vulnerability to me?
This vulnerability is a memory leak in the Linux kernel's mt76 wifi driver. Specifically, it occurs in the mt76_dma_tx_cleanup routine, where device unregistering did not properly clean up all configured receive (rx) queues, leading to a memory leak. The issue has been fixed by ensuring all rx queues are always cleaned up during this routine.
How can this vulnerability impact me? :
The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing instability in devices using the affected mt76 wifi driver. This could result in reduced reliability or crashes related to wifi functionality.
