Out-of-Bounds Read in SICK AppSpace Application

Executive Summary

CVE-2026-101290 is an out-of-bounds read vulnerability in the Sick_Safetyscanners_Base C++ driver library (versions 1.0.4 and earlier). A remote attacker can send a specially crafted network packet that causes the library to read memory outside the intended buffer due to insufficient packet length validation. This may lead to application crashes and denial-of-service conditions.

Compliance Impact

This vulnerability primarily causes denial-of-service conditions by crashing applications, which may impact availability of systems. While it does not directly expose or leak data, prolonged downtime could affect compliance with regulations requiring continuous availability of critical systems, such as HIPAA for healthcare operations or GDPR for data processing systems. However, the provided context does not specify direct impacts on compliance.
