CVE-2026-112046

A flaw was found in OW2 ASM. An attacker can cause a Denial of Service (DoS) by supplying a specially crafted Java class file with methods that grow beyond 64 kilobytes during transformation. When processing this file, an offset truncation error triggers an infinite loop within the method resolution logic, causing the application reading or analyzing the class file to hang indefinitely.

5.5 (Medium)

CVE-2026-112046 (GCVE-0-2026-112046)

Vulnerability from cvelistv5 – Published: 2026-10-18 12:19 – Updated: 2026-10-19 16:38

Title

OW2 ASM 9.11 before 9.11.1 Denial of Service via Infinite Loop in Label.resolve()

Summary

OW2 ASM 9.11 before 9.11.1 contains an infinite loop vulnerability in Label.resolve() caused by 16-bit forward-reference offsets truncating when rewritten methods exceed 64 KB. Attackers can supply crafted class files whose transformed code grows past 65535 bytes, hanging ClassReader.accept() and denying service to build tools, instrumenters, agents, or analyzers.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
