CVE-2026-24406
Published: 24 January 2026
Summary
CVE-2026-24406 is a high-severity Improper Input Validation (CWE-20) vulnerability in Color Iccdev. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 34.3th 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Implements memory protection safeguards like address space layout randomization and stack guards to prevent heap buffer overflows during processing of untrusted ICC profile data.
Requires validation of user-controllable inputs such as ICC profile data to ensure proper size and structure before incorporation into binary blobs, directly addressing CWE-20 improper input validation.
Mandates timely identification, reporting, and patching of flaws like the heap buffer overflow in iccDEV versions 2.3.1.1 and below, aligning with the vendor fix in 2.3.1.2.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Heap buffer overflow in iccDEV library enables arbitrary code execution via malicious ICC profiles processed by client applications, directly facilitating T1203: Exploitation for Client Execution.
NVD Description
iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. Versions 2.3.1.1 and below have a Heap Buffer Overflow vulnerability in CIccTagNamedColor2::SetSize(). This occurs when user-controllable input is unsafely incorporated into ICC profile data or…

other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and Code Execution. This issue has been fixed in version 2.3.1.2.
Deeper analysisAI
CVE-2026-24406 is a Heap Buffer Overflow vulnerability in the iccDEV library and tools, which are used for interacting with, manipulating, and applying ICC color management profiles. The flaw resides in the CIccTagNamedColor2::SetSize() function and affects versions 2.3.1.1 and below. It arises when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs, as associated with CWE-20 (Improper Input Validation) and CWE-122 (Heap-based Buffer Overflow).
The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating it is exploitable over the network with low attack complexity, no privileges, and user interaction required, such as opening a malicious ICC profile. Remote attackers can leverage specially crafted input to trigger the overflow, potentially achieving denial of service, data manipulation, bypassing application logic, or arbitrary code execution in applications that process ICC profiles via iccDEV.
The vulnerability has been addressed in iccDEV version 2.3.1.2. Mitigation involves updating to this patched release. Additional details are available in the GitHub security advisory (GHSA-h9h3-45cm-j95f), the related issue tracker (issues/480), and the fixing commit (90c71cba2c563b1f5dc84197f827540d1baaea67).
