ffmpeg: A flaw was found in FFmpeg’s TensorFlow backend within the libavfilter/dnn_backend_tf.c source file
CVE-2025-12343 is fixed in 15 products on 1 platform, first by DEBIAN-CVE-2025-12343, released February 18, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in FFmpeg’s TensorFlow backend within the libavfilter/dnn_backend_tf.c source file. 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.
