CVE-2025-11274 identifies a resource allocation vulnerability in the Open Asset Import Library (Assimp) version 6.0.2, specifically within the Q3DImporter::InternReadFile function located in the source file assimp/code/AssetLib/Q3D/Q3DLoader.cpp. This vulnerability arises from improper handling of resource allocation when processing Q3D files, which can lead to excessive consumption of system resources such as memory or CPU cycles. The flaw is exploitable only through local execution, meaning an attacker must have some level of access to the host system to trigger the vulnerability. The attack vector requires low privileges (PR:L) and does not require user interaction (UI:N). The vulnerability does not compromise confidentiality, integrity, or availability directly but can cause resource exhaustion, potentially resulting in denial of service or degraded system performance. The CVSS 4.0 score of 4.8 reflects a medium severity level, indicating moderate risk. No public patches or fixes are currently linked, and no known exploits have been observed in the wild. The vulnerability was publicly disclosed shortly after being reserved, indicating timely awareness but no immediate widespread exploitation. Assimp is widely used in applications that import and process 3D asset files, including game development, CAD software, and visualization tools, making this vulnerability relevant to environments where such software is deployed.

For European organizations, the primary impact of CVE-2025-11274 is the potential for local denial of service or system instability due to resource exhaustion when processing malicious or malformed Q3D files using Assimp 6.0.2. This could disrupt workflows in industries relying on 3D modeling and asset importation, such as gaming, automotive design, architecture, and manufacturing. While the vulnerability does not allow remote exploitation or data compromise, the requirement for local access means insider threats or compromised endpoints could leverage this flaw to degrade system availability. Organizations with development environments or production systems that utilize Assimp for 3D asset processing may experience reduced productivity or require system restarts to recover from resource depletion. The absence of remote exploitation limits the threat surface, but the vulnerability still poses operational risks, especially in environments with shared workstations or build servers. The impact on confidentiality and integrity is negligible, but availability degradation could affect critical design and simulation processes.

To mitigate CVE-2025-11274, European organizations should first identify all systems running Assimp version 6.0.2, particularly those processing Q3D files. Since no official patch is currently available, organizations should consider the following specific actions: 1) Restrict local access to systems running vulnerable Assimp versions to trusted users only, minimizing the risk of exploitation by unauthorized personnel. 2) Implement monitoring of resource usage during 3D asset import operations to detect abnormal spikes indicative of exploitation attempts. 3) Where feasible, sandbox or isolate processes that invoke Assimp to limit the impact of resource exhaustion on the broader system. 4) Review and harden endpoint security controls to prevent unauthorized local access or privilege escalation that could facilitate exploitation. 5) Engage with the Assimp project or vendors for updates and apply patches promptly once released. 6) Consider upgrading to newer Assimp versions if they contain fixes or mitigations for this vulnerability. 7) Educate developers and users about the risks of processing untrusted 3D asset files and enforce file validation policies.
