CVE-2019-19073: Medium severity Linux Linux kernel vulnerability

Published Nov 18, 2019
·
Updated

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

Other sources

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 waitforcompletiontimeout() failures during device initialisation or USB device probing.

This affects the htcconfigpipecredits() function, the htcsetupcomplete() function, and the htcconnectservice() function.
