CVE-2019-19073

Published: 18 November 2019

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.

From the Ubuntu security team

It was discovered that the Atheros HTC based wireless driver in the Linux kernel did not properly deallocate in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion).

Priority

Low

CVSS 3 base score: 4.0
