Substance3D - Stager is affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

The version of Adobe Substance 3D Stager installed on the remote macOS host is prior to 3.1.9. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB26-170 advisory.

  - Substance3D - Stager is affected by a Use After Free 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-2026-103843)

  - Substance3D - Stager is affected by a Stack-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-2026-103830, CVE-2026-103851)

  - Substance3D - Stager is affected by an out-of-bounds write 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-2026-103832, CVE-2026-103833, CVE-2026-103834,     CVE-2026-103835, CVE-2026-103836, CVE-2026-103837, CVE-2026-103838, CVE-2026-103839)

  - Substance3D - Stager is affected by an out-of-bounds read vulnerability when parsing a crafted file, which     could result in a read past the end of an allocated memory structure. An attacker could leverage this     vulnerability to execute code in the context of the current user. Exploitation of this issue requires user     interaction in that a victim must open a malicious file. (CVE-2026-103840, CVE-2026-103841,     CVE-2026-103842)

  - Substance3D - Stager is affected by an out-of-bounds read vulnerability that could lead to disclosure of     sensitive memory. An attacker could leverage this vulnerability to disclose sensitive information.
    Exploitation of this issue requires user interaction in that a victim must open a malicious file.
