An issue was discovered in write_tpt_entry in
drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The
cxgb4 driver is directly calling dma_map_single (a DMA function) from a
stack variable. This could allow an attacker to trigger a Denial of
Service, exploitable if this driver is used on an architecture for which
this stack/DMA interaction has security relevance.
