  "details": "In the Linux kernel, the following vulnerability has been resolved:  can: ucan: Fix infinite loop from zero-length messages  If a broken ucan device gets a message with the message length field set to 0, then the driver will loop for forever in ucan_read_bulk_callback(), hanging the system.  If the length is 0, just skip the message and go on to the next one.  This has been fixed in the kvaser_usb driver in the past in commit 0c73772cd2b8 (\"can: kvaser_usb: leaf: Fix potential infinite loop in command parsers\"), so there must be some broken devices out there like this somewhere.",
