Podatność CVE-2019-17075


Publikacja: 2019-10-01

Opis:
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.

Typ:

CWE-119

Producent: Linux
Produkt: Linux kernel 
Wersje: 5.3.2;
