kernel: Null pointer dereference in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c
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.
A null pointer dereference flaw was found in the flexcop_usb_probe function in the Flexcop digital TV device driver. An attacker who can insert a malicious USB device into the system could use this flaw to crash the system.
Mitigation: As the b2c2-flexcop-usb module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:
# echo "install b2c2-flexcop-usb /bin/true" >> /etc/modprobe.d/disable-b2c2
