JSON

In the Linux kernel through 5.4.6, there are information leaks of
uninitialized memory to a USB device in the
drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka
CID-da2311a6385c.

Notes

Author	Note
tyhicks	I don’t think that the Fixes tag in patch is correct and that the info leaks were possible since the initial inclusion of the driver
