CVE-2019-15291

Priority

Description

An issue was discovered in the Linux kernel through 5.2.9. There is a NULL
pointer dereference caused by a malicious USB device in the
flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c
driver.

Ubuntu-Description

It was discovered that the B2C2 FlexCop USB device driver in the Linux
kernel did not properly validate device metadata. A physically proximate
attacker could use this to cause a denial of service (system crash).
