CVE-2025-15666
Description
A flaw was found in Assimp, the Open Asset Import Library. A local attacker could exploit a vulnerability where specially crafted model files could cause a heap-based buffer overflow. This issue, occurring in the SceneCombiner::Copy function, could allow an attacker to gain unauthorized access to sensitive information or cause the application to crash, leading to a denial of service.
Statement
Successful exploitation requires local access and user interaction. An attacker must supply a specially crafted model file and rely on a user or an application to actively process it using the Assimp library.
The impact of this vulnerability is localized specifically to the application parsing the malformed file. While it can lead to an application crash (Denial of Service) or localized information disclosure, it does not allow for privilege escalation, remote code execution, or a broader system-wide compromise.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
