Summary

CVE-2025-10994 is a low-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Openbabel Open Babel. Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-16 (Memory Protection) — see the control section below for these in your framework.

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
Why these techniques?

Use-after-free vulnerability in Open Babel allows arbitrary code execution when processing crafted GAMESS output files, facilitating exploitation of client-side software vulnerabilities.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly implements memory protections that block use-after-free exploitation in functions such as GAMESSOutputFormat::ReadMolecule.

prevent

Requires validation of untrusted molecule input files before they reach the vulnerable parser, preventing trigger of the CWE-416 flaw.

prevent

Isolates the Open Babel process so that a local use-after-free cannot affect other system components or escalate privileges.

detects

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.

prevents

Change-management processes help ensure memory-safety fixes are deployed consistently.
