CVE-2019-20095
First published: Mon Dec 30 2019(Updated: )
A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted.
