- Summary
- net: xilinx: axienet: Enqueue Tx packets in dql before dmaengine starts
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: xilinx: axienet: Enqueue Tx packets in dql before dmaengine starts
Enqueue packets in dql after dma engine starts causes race condition. Tx transfer starts once dma engine is started and may execute dql dequeue in completion before it gets queued. It results in following kernel crash while running iperf stress test:
