"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-002328 advisory.

    Integer overflow in the LZ4 algorithm implementation, as used in Yann Collet LZ4 before r118 and in the
    lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit platforms
    might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have
    unspecified other impact via a crafted Literal Run that would be improperly handled by programs not
    complying with an API limitation, a different vulnerability than CVE-2014-4715.

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.");
