The vulnerability identified as CVE-2026-21675 affects the iccDEV library, which provides tools for working with ICC color management profiles. A Use After Free vulnerability exists in the CIccXform::Create() function in versions 2.3.1 and below. This vulnerability allows attackers to potentially exploit the application by manipulating memory references. The issue has been addressed in version 2.3.1.1, highlighting the urgency for organizations using this library to apply the necessary updates.
With a CVSS score of 9.8, this vulnerability is classified as critical. The high severity indicates a significant risk to organizations that utilize the affected iccDEV library. The potential for exploitation through network access and the low attack complexity means that attackers could gain unauthorized access or execute arbitrary code with minimal effort.
The risk to organizations includes potential data exposure, loss of integrity, and availability issues due to the vulnerability's nature. Given the criticality of this finding, organizations should prioritize patching immediately.
As of now, there are no public exploits reported, and the vulnerability is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and monitor for any related threat activity.
Vulnerability Details
CVE-2026-21675 is characterized by a Use After Free vulnerability within the CIccXform::Create() function of iccDEV. The affected versions are 2.3.1 and earlier, with the vulnerability fixed in version 2.3.1.1. This flaw falls under the CWE-20 (Improper Input Validation) and CWE-416 (Use After Free) categories, indicating both inadequate input handling and unsafe memory management.
The CVSS v3.1 score of 9.8 highlights the critical nature of this vulnerability, which has high impacts on confidentiality, integrity, and availability. This emphasizes the importance of addressing this issue promptly.
Organizations using iccDEV should ensure they update to version 2.3.1.1 or later to mitigate this critical vulnerability.
Technical Analysis
The root cause of the vulnerability stems from improper memory management within the CIccXform::Create() function. When the function deletes the hint without ensuring proper checks, it creates an opportunity for a Use After Free scenario. This vulnerability is exploited over a network, requiring no special privileges or user interaction, indicating a high risk factor.
The attack complexity is low, as attackers can exploit the vulnerability without any significant barriers. The potential impacts are severe, affecting confidentiality, integrity, and availability, which can lead to unauthorized access or denial of service.
Risk & Impact Analysis
Organizations using the vulnerable version of iccDEV are at significant risk. The vulnerability's critical nature means that successful exploitation could result in substantial data breaches and system failures. The blast radius is considerable, given the potential for network-based exploitation and the criticality of the library in color management applications.
Despite the low EPSS score indicating a lower likelihood of exploitation, the critical CVSS score necessitates immediate action. Organizations must prioritize remediation efforts, ensuring that they are updated to the latest version of iccDEV to prevent potential exploits.
