TIMELINE

Sep 16 PATCH SHIPPED — CVE-2026-85197 (Red Hat Enterprise Linux 10). Fixed in Red Hat Enterprise Linux 10 0:3.6.5-3.el10_2.14.
Description
A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle (MITM) attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file body is being read asynchronously. This can lead to memory corruption, potentially resulting in information disclosure or arbitrary code execution.
