  "summary": "CVE-2026-85197 is fixed in 10 products on 1 platform, first by gir1.2-soup-3.0 3.0.7-0ubuntu1\u002Besm9, released September 4, 2026. It is not reported as exploited. Patch Radar priority: High.",
  "title": "Libsoup: libsoup: heap use-after-free in libsoup http/2 client on_data_read() via goaway during body upload",
  "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.",
