CVE-2019-15220

Published: 19 August 2019

An issue was discovered in the Linux kernel before 5.2.1. There is a use-after-free caused by a malicious USB device in the drivers/net/wireless/intersil/p54/p54usb.c driver.

From the Ubuntu Security Team

It was discovered that a race condition existed in the Softmac USB Prism54 device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash).
