CVE-2019-15215
Published: 19 August 2019
An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/usb/cpia2/cpia2_usb.c driver.
From the Ubuntu Security Team
It was discovered that a race condition existed in the CPiA2 video4linux device driver for the Linux kernel, leading to a use-after-free. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
