Описание
In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_pro.c driver, aka CID-ead16e53c2f0.
A flaw was found in the Linux kernel’s implementation of the driver for the PEAK System PCAN-USB adapter. On device initialization, the driver can leak information to all devices connected to the CANBUS.
Меры по смягчению последствий
As the pcan_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 pcan_usb /bin/true" >> /etc/modprobe.d/disable-pcan_usb.conf
The system will need to be restarted if the module is loaded. In most circumstances, the pcan_usb kernel modules will be unable to be unloaded while any CANBUS interfaces are active and the protocol is in use. If the system requires this module to work correctly, this mitigation may not be suitable. If you need further assistance, see KCS article https://access.redhat.com/solutions/41278 or contact Red Hat Global Support Services.
