CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2026-21353 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Adobe Dng Software Development Kit. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-21353 is an Integer Overflow or Wraparound vulnerability (CWE-190) affecting Adobe DNG SDK versions 1.7.1 2410 and earlier. The flaw could result in arbitrary code execution in the context of the current user.
Exploitation requires local access (AV:L) with low complexity (AC:L) and no privileges (PR:N), but necessitates user interaction (UI:R) in the form of opening a malicious file. A successful attack achieves high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the user's scope (S:U), earning a CVSS v3.1 base score of 7.8.
Adobe's security bulletin APSB26-23, available at https://helpx.adobe.com/security/products/dng-sdk/apsb26-23.html, addresses this issue with details on patches and mitigation.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.
Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.
Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require use of safe arithmetic, bounds checks, and testing that prevent integer overflows.

Security testing in development can detect integer overflows before release.
Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.
Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
