Descriptions

Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function, aka CID-853acf7caf10.

Pérdidas de memoria en el archivo drivers/net/wireless/ath/ath9k/htc_hst.c en el kernel de Linux versiones hasta la versión 5.3.11, permiten a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función wait_for_completion_timeout(). Esto afecta la función htc_config_pipe_credits(), la función htc_setup_complete() y la función htc_connect_service(), también se conoce como CID-853acf7caf10.
