Description Marian Rehak 2019-11-21 10:17:38 UTC
Memory leaks in the kernels implementation of Host/Target communications of the atheros wifi driver in the Linux kernel which allows a local attacker to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures during device initialisation or USB device probing. 

This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function.
