How to fix?

Upgrade Oracle:9 libsoup to version 0:2.72.0-16.el9_8.8 or higher.
This issue was patched in ELSA-2026-83384.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup package and not the libsoup package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.
