Summary

CVE-2026-34546 is a medium-severity Divide By Zero (CWE-369) vulnerability in Color Iccdev. Its CVSS base score is 6.2 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including static/dynamic analysis) finds divide-by-zero conditions after they have been coded.

Security engineering principles can require safe-arithmetic constructs or explicit guards that keep division operands nonzero.

Validating numeric inputs before use as divisors structurally blocks zero values from reaching division operations.

finds

Security testing in development can detect divide-by-zero conditions before release.

prevents

Secure development lifecycle includes input validation and error-handling practices that can prevent divide-by-zero faults.

prevents

Application security requirements can mandate checks for zero denominators and safe arithmetic handling.

prevents

Secure architecture principles encourage defensive coding patterns that avoid arithmetic exceptions.

prevents

Secure coding standards directly require validation to prevent divide-by-zero and similar runtime faults.
