"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-002089 advisory.

    The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before
    3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-
    dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute
    arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an
    AF_ALG(aead) socket.

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.");
