CVE-2026-53298 is a vulnerability in Linux Kernel
Published on June 26, 2026
net: airoha: Move ndesc initialization at end of airoha_qdma_init_rx_queue()
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.
