medium Nessus Plugin ID 280494
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992330 advisory.In the Linux kernel, the following vulnerability has been resolved:
crypto: cavium - prevent integer overflow loading firmware
The code_length value comes from the firmware file. If your firmware is untrusted realistically there is probably very little you can do to protect yourself. Still we try to limit the damage as much as possible.
Also Smatch marks any data read from the filesystem as untrusted and prints warnings if it not capped correctly.
The ntohl(ucode->code_length) * 2 multiplication can have an integer overflow.
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected kernel package.See Also
