CVE-2026-23298

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