How to fix?

Upgrade torvalds/linux to version 5.3.3 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). 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.
