The vulnerability CVE-2026-22047 affects iccDEV, a library used for handling ICC color profiles, which are widely used in color management across various software and hardware systems. The flaw is a heap-buffer-overflow in the SIccCalcOp::Describe() function located in the IccProfLib/IccMpeCalc.cpp source file. This vulnerability stems from improper input validation (CWE-20) and buffer handling issues (CWE-130), leading to potential memory corruption. When an attacker crafts a malicious ICC profile and convinces a user or system to process it, the overflow can be triggered, enabling arbitrary code execution, data corruption, or denial of service. The vulnerability has a CVSS v3.1 score of 8.8, indicating high severity, with attack vector being network-based, no privileges required, but user interaction necessary (e.g., opening or processing a malicious file). The scope is unchanged, meaning the impact is confined to the vulnerable component but can affect confidentiality, integrity, and availability. The patched version 2.3.1.2 addresses this issue, but no alternative mitigations or workarounds are available. Although no exploits have been observed in the wild yet, the potential impact on systems that rely on iccDEV for color profile processing is significant, especially in environments where untrusted ICC profiles might be processed automatically or by end users.

For European organizations, the impact of this vulnerability can be substantial, particularly for industries relying heavily on color management workflows, such as digital printing, graphic design, photography, and media production. Exploitation could lead to remote code execution, allowing attackers to gain control over affected systems, steal sensitive data, disrupt services, or pivot within networks. This could compromise intellectual property, disrupt business operations, and damage reputations. Since ICC profiles are often embedded in image files or documents, the attack surface includes email attachments, downloaded files, or shared media. Organizations that automate processing of ICC profiles without strict validation are at higher risk. The lack of known exploits currently provides a window for proactive patching, but the high CVSS score and ease of exploitation underline the urgency. Additionally, supply chain risks exist if third-party software or hardware integrates vulnerable iccDEV versions, potentially expanding the impact beyond direct users.

1. Immediately update all instances of iccDEV to version 2.3.1.2 or later to apply the official patch. 2. Audit all software and hardware components in your environment that utilize iccDEV or process ICC profiles to identify vulnerable versions. 3. Implement strict input validation and filtering on ICC profiles, especially those received from untrusted or external sources. 4. Restrict or monitor the processing of ICC profiles in automated workflows to prevent inadvertent exploitation. 5. Employ endpoint protection solutions capable of detecting anomalous behavior indicative of heap overflows or code execution attempts. 6. Educate users about the risks of opening untrusted image files or documents containing ICC profiles. 7. Coordinate with vendors and suppliers to ensure patched versions are deployed in third-party products incorporating iccDEV. 8. Monitor threat intelligence feeds for any emerging exploit activity related to this vulnerability to respond promptly.
