Description OSIDB Bzimport 2025-10-27 12:54:46 UTC
Double-Free vulnerability in the TensorFlow DNN backend of the FFmpeg multimedia framework. The flaw resides in the dnn_execute_model_tf() function, where a task object is improperly freed multiple times using av_freep() under certain error conditions. Because the same task is also released later by dnn_free_model_tf() after a successful queue push, this leads to a double-free and subsequent memory corruption. An attacker could exploit this issue by feeding crafted data to a process using FFmpeg’s DNN TensorFlow backend, triggering a crash and causing a denial of service.
