The issue occurs in the dnn_execute_model_tf() function, where a task object is freed multiple times in certain error-handling paths. This redundant memory deallocation can lead to a double-free condition, potentially causing FFmpeg or any application using it to crash when processing TensorFlow-based DNN models. This results in a denial-of-service scenario but does not allow arbitrary code execution under normal conditions.","status":"published","published":"2026-02-18T21:16:00Z","modified":"2026-10-17T12:57:00.903758548Z","cvss":[{"version":"3.1","score":3.3,"vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","level":"low"},{"version":"3.1","score":5.5,"vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","level":"medium"}],"updated_at":"2026-11-02T16:55:20.144818Z"},{"id":"DSA-6007-1","title":"ffmpeg - security update","status":"published","published":"2025-09-21T00:00:00Z","modified":"2026-03-09T02:09:39.708124Z","updated_at":"2026-11-02T15:46:18.296714Z"},{"id":"USN-8469-1","title":"ffmpeg vulnerabilities","description":"Jiasheng Jiang discovered that FFmpeg incorrectly handled memory in\ncertain error-handling paths of its TensorFlow DNN backend.
