CVE-2026-10229
Description
A flaw was found in Assimp, a library used for importing and exporting various 3D model formats. This vulnerability, a heap-based buffer overflow, exists within the HL1MDLLoader::read_meshes function of the Half-Life 1 MDL Loader component. A local attacker could exploit this by providing specially crafted input, which may lead to a denial of service, information disclosure, or other impacts on system integrity.
Statement
This Moderate flaw in Assimp's Half-Life 1 MDL Loader component, specifically within the HL1MDLLoader::read_meshes function, is a heap-based buffer overflow. Exploitation requires a local attacker to provide specially crafted input, which could lead to denial of service or information disclosure. While the exploit is publicly known, the local attack vector limits its immediate impact on typical Red Hat deployments.
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,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
