An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
    (CVE-2026-23298)

Note that Nessus relies on the presence of the package as reported by the vendor.
