Vulnerability from github – Published: 2026-06-26 21:32 – Updated: 2026-07-08 06:31

Details

In the Linux kernel, the following vulnerability has been resolved:

net: airoha: Move ndesc initialization at end of airoha_qdma_init_rx_queue()

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

Severity

5.5 (Medium)
