CVE-2019-19073: Fedoraproject Fedora

Medium severity, CVSS 4.0. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 30 only; version 31 only
• Linux Linux Kernel: up to and including 5.3.11
• Opensuse Leap: version 15.1 only
