Exploitation evidence

Disclosed: evidence found.
CVE published 4 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat has released updated qt5-qt3d packages for Red Hat Enterprise Linux 9.2 that address these vulnerabilities. Users should apply the security update as described in the Red Hat advisory RHSA-2025:15347. Patch status is confirmed with official fixes available. No additional mitigation steps are specified by the vendor.

Description

Qt 3D provides functionality for near-realtime simulation systems with support for 2D and 3D rendering in both Qt C++ and Qt Quick applications). Security Fix(es): * assimp: Open Asset Import Library Assimp LWO File LWOAnimation.cpp UpdateAnimRangeSetup heap-based overflow (CVE-2025-3158) * assimp: Open Asset Import Library Assimp ASE File ASEParser.cpp ParseLV4MeshBonesVertices heap-based overflow (CVE-2025-3159) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Successful exploitation of these heap-based buffer overflow vulnerabilities could lead to memory corruption, which may cause application crashes or potentially allow code execution depending on the context. The advisory rates the security impact as moderate. There are no known exploits in the wild at this time.

Summary

The vulnerabilities CVE-2025-3158 and CVE-2025-3159 are heap-based buffer overflows in the Open Asset Import Library (assimp) used by qt5-qt3d, specifically in LWOAnimation.cpp's UpdateAnimRangeSetup function and ASEParser.cpp's ParseLV4MeshBonesVertices function. These flaws could allow an attacker to cause memory corruption when processing crafted LWO or ASE files. Red Hat Product Security has rated the impact as moderate and released updated qt5-qt3d packages for Red Hat Enterprise Linux 9.2 to remediate these issues.
