Descriptions

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.

Se detectó un problema en la función write_tpt_entry en el archivo drivers/infiniband/hw/cxgb4/mem.c en el kernel de Linux versiones hasta 5.3.2. El controlador cxgb4 está llamando directamente a dma_map_single (una función DMA) desde una variable de la pila. Esto podría permitir que un atacante desencadene una Denegación de Servicio, explotable si este controlador es utilizado en una arquitectura para la cual esta interacción pila/DMA tiene relevancia de seguridad.
