What to do
AI-suggested
A fix has been implemented in the Linux kernel to address this memory leak. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
Description
A memory leak vulnerability was fixed in the Linux kernel's airoha network driver function airoha_qdma_rx_process(). The leak occurs when errors happen on subsequent buffers of the non-linear part of the socket buffer (skb), causing page_pool fragments not to be returned to the pool. This issue was addressed by ensuring the page_pool_put_full_page routine is always called in the error path.
