CVE-2026-53298

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: airoha: Move ndesc initialization at end of airoha_qdma_init_rx_queue()<br /> <br /> If queue entry or DMA descriptor list allocation fails in<br /> airoha_qdma_init_rx_queue routine, airoha_qdma_cleanup() will trigger a<br /> NULL pointer dereference running netif_napi_del() for RX queue NAPIs<br /> since netif_napi_add() has never been executed to this particular RX NAPI.<br /> The issue is due to the early ndesc initialization in<br /> airoha_qdma_init_rx_queue() since airoha_qdma_cleanup() relies on ndesc<br /> value to check if the queue is properly initialized. Fix the issue moving<br /> ndesc initialization at end of airoha_qdma_init_tx routine.<br /> Move page_pool allocation after descriptor list allocation in order to<br /> avoid memory leaks if desc allocation fails.
