Information Disclosure AI / ML Xgrammar Redhat

Description

xgrammar is an open-source library for efficient, flexible, and portable structured generation. Prior to version 0.1.32, the multi-level nested syntax caused a segmentation fault (core dumped). This issue has been patched in version 0.1.32.

Analysis

Xgrammar versions prior to 0.1.32 crash when processing multi-level nested syntax structures, causing a denial of service that halts the application. An attacker can trigger this segmentation fault remotely without authentication by submitting crafted input, disrupting any AI/ML system relying on this library for structured generation tasks. …
