AI-suggested
No fixes are currently available for Red Hat AI Base Images 3.5.6 (Rubin). For affected Node.js and .NET packages, update the system brotli/libbrotli package where applicable. Red Hat's platform hardenings provide some mitigation by increasing exploitation difficulty. Follow the detailed mitigation procedures in the Red Hat security bulletin RHSB-2026:015. Customers with a Technical Account Manager (TAM) can consult directly for tailored guidance.
Description
CVE-2026-111497 is a vulnerability in the Google Brotli decoder used in Red Hat AI Base Images and other Red Hat products. It involves an out-of-bounds write triggered by a crafted Brotli-compressed stream, potentially leading to memory disclosure, denial of service, or arbitrary code execution when decompressing untrusted Brotli data. Exploitation requires a malformed Brotli stream and is rated as having high attack complexity due to Red Hat's platform hardenings. No fixes are currently available for Red Hat AI Base Images 3.5.6 (Rubin).
