Summary

CVE-2026-31795 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Color Iccdev. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 2.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly mandates timely remediation of the stack buffer overflow flaw in iccDEV by patching to version 2.3.1.5 or later, preventing exploitation.

prevent

Implements memory safeguards like stack canaries and DEP to block unauthorized code execution from the stack buffer overflow in CIccXform3DLut::Apply().

detect

Enables scanning and monitoring to identify systems running vulnerable iccDEV versions affected by CVE-2026-31795 for prioritized patching.

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
T1204.002 Malicious File Execution
An adversary may rely upon a user opening a malicious file in order to gain execution.
Why these techniques?

Stack buffer overflow in client-side ICC profile parser directly enables T1203 (Exploitation for Client Execution) when triggered by a malicious file that a user is tricked into opening (T1204.002).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to 2.3.1.5, there is a stack buffer overflow write in CIccXform3DLut::Apply() corrupting stack memory or crash. This vulnerability is fixed in 2.3.1.5.

Deeper analysisAI

CVE-2026-31795 is a stack buffer overflow vulnerability affecting iccDEV, a set of libraries and tools for working with ICC color management profiles. In versions prior to 2.3.1.5, the CIccXform3DLut::Apply() function contains a stack buffer overflow write that can corrupt stack memory or cause an application crash. Published on 2026-03-10, the issue maps to CWE-120 (buffer copy without checking size), CWE-121 (stack-based buffer overflow), and CWE-787 (out-of-bounds write), with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

The vulnerability can be exploited by a local attacker with no privileges who tricks a user into processing a malicious ICC profile, requiring user interaction such as opening a specially crafted file in an application that uses iccDEV. Successful exploitation leads to high-impact consequences, including potential arbitrary code execution, data tampering, or denial of service via stack memory corruption.

Mitigation is available in iccDEV version 2.3.1.5, which includes a fix for the overflow. The GitHub security advisory (GHSA-wh5x-j6pq-pr3c), issue #649, pull request #655, and release tag v2.3.1.5 provide details on the patch and resolution. Security practitioners should update dependent applications to 2.3.1.5 or later to prevent exploitation.
