Description
In the Linux kernel, the following vulnerability has been resolved: net: airoha: Fix memory leak in airoha_qdma_rx_process() If an error occurs on the subsequents buffers belonging to the non-linear part of the skb (e.g. due to an error in the payload length reported by the NIC or if we consumed all the available fragments for the skb), the page_pool fragment will not be linked to the skb so it will not return to the pool in the airoha_qdma_rx_process() error path. Fix the memory leak partially reverting commit 'd6d2b0e1538d ("net: airoha: Fix page recycling in airoha_qdma_rx_process()")' and always running page_pool_put_full_page routine in the airoha_qdma_rx_process() error path.
