    CVE-2026-48420, CVE-2026-48421)

  - Substance3D - Sampler is affected by a Heap-based Buffer Overflow vulnerability that could result in
    arbitrary code execution in the context of the current user. Exploitation of this issue requires user
    interaction in that a victim must open a malicious file. (CVE-2026-48422, CVE-2026-48423,
    CVE-2026-48424, CVE-2026-48425)

  - Substance3D - Sampler is affected by a Stack-based Buffer Overflow vulnerability that could result in

    interaction in that a victim must open a malicious file. (CVE-2026-48417)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
