CVE-2026-43102 Details
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.
A memory leak vulnerability has been identified in the Linux kernel's Airoha network driver. This issue arises in the 'airoha_qdma_rx_process()' function when an error occurs with the non-linear part of the socket buffer (skb). Such errors can be triggered by incorrect payload length reports from the network interface card (NIC) or by exhausting all available fragments for the skb. In these scenarios, the page_pool fragment fails to link back to the skb, preventing it from returning to the pool during the error handling process. The vulnerability has been addressed by partially reverting a previous commit and ensuring that the 'page_pool_put_full_page' routine is always executed in the error path of 'airoha_qdma_rx_process()'.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
