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.
