CVE-2026-110260
Description
A flaw was found in OW2 ASM. An attacker can trigger a Denial of Service (DoS) by providing a specially crafted Java class file containing numerous overlapping exception handlers. When the library analyzes the method stack or frame structures of such a file, it performs excessive memory allocation, leading to an out-of-memory condition that crashes the Java Virtual Machine (JVM).
Statement
Red Hat has classified this vulnerability as having Moderate severity because exploitation requires local user interaction to process untrusted compiled code, and the impact is limited strictly to a denial of service without exposing data or allowing code execution. Within Red Hat environments, the affected library is typically embedded in build automation tools such as Maven or class instrumentation frameworks rather than services exposed directly to network clients. An attacker would need to trick a user or automated pipeline into analyzing a malicious binary artifact to cause a process crash. Typical server deployments that only consume verified artifacts are not exposed to this issue during normal operations.
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).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
