CVE-2019-19073 is a medium-severity vulnerability rated 4/10 on the CVSS scale. 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.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
