Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-85197)
