"The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has a package installed that is affected by a vulnerability as
referenced in the USN-5493-1 advisory.
It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly
handle certain error conditions, leading to a double-free. A local attacker could possibly use this to
cause a denial of service (system crash).
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
