"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-416704 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    crypto: caam - Fix the pointer passed to caam_qi_shutdown()

    The type of the last parameter given to devm_add_action_or_reset() is
    struct caam_drv_private *, but in caam_qi_shutdown(), it is casted to
    struct device *.

    Pass the correct parameter to devm_add_action_or_reset() so that the
    resources are released as expected.

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.");
