CVE-2019-17075

Published: 1 October 2019

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.

From the Ubuntu security team

Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux kernel performed DMA from a kernel stack. A local attacker could use this to cause a denial of service (system crash).

Priority
