"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: ucan: Fix infinite loop from zero-length messages\n\nIf a broken ucan device gets a message with the message length field set\nto 0, then the driver will loop for forever in\nucan_read_bulk_callback(), hanging the system. If the length is 0, just\nskip the message and go on to the next one.\n\nThis has been fixed in the kvaser_usb driver in the past in commit\n0c73772cd2b8 (\"can: kvaser_usb: leaf: Fix potential infinite loop in\ncommand parsers\"), so there must be some broken devices out there like\nthis somewhere."
