CVE-2019-15218

Published: 19 August 2019

An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver.

From the Ubuntu Security Team

It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel made improper assumptions about the device characteristics. A physically proximate attacker could use this cause a denial of service (system crash).
