NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup3-doc package and not the libsoup3-doc package as distributed by Centos. See How to fix? for Centos:10 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.
