gvfs: A flaw was found in the AFP backend in gvfs
CVE-2026-84269 is fixed in 6 products on 1 platform, first by gvfs 1.48.2-0ubuntu1.3, released September 1, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in the AFP backend in gvfs. When mounting a share, a malicious AFP server can cause the DSI read path to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the pre-sized reply buffer, causing the operation to access past the intended boundaries. This issue allows a malicious server to overflow a heap buffer and crash the gvfsd-afp process, resulting in a denial of service.
