AI-suggested
For other affected products using Brotli, updating system Brotli packages is recommended. Red Hat platform hardenings such as ASLR, NX, FORTIFY_SOURCE, and SELinux provide some mitigation against exploitation. Avoid decompressing untrusted Brotli data where possible until a fix is released.
Description
CVE-2026-96889 affects Red Hat AI Base Images 3.5.6 (Spyre). It is associated with vulnerabilities in the Google Brotli decoder, specifically an out-of-bounds write triggered by crafted Brotli-compressed streams. This flaw can lead to memory disclosure, denial of service, or potentially arbitrary code execution when decompressing untrusted Brotli data. Red Hat rates this issue as Important with high attack complexity due to required conditions for exploitation and platform hardenings that mitigate reliable code execution.
