AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a memory leak in the Linux kernel's net: libwx component. Specifically, when the function wx_alloc_page_pool() fails during wx_setup_rx_resources(), the DMA buffer is not released properly, leading to a memory leak. The fix involves adding dma_free_coherent() in the error path to release the DMA buffer.
How can this vulnerability impact me? :
The memory leak caused by this vulnerability can lead to increased memory usage and potential resource exhaustion on affected systems, which may degrade system performance or cause instability over time.
