CVE-2025-12343: A flaw was found in FFmpeg’s TensorFlow backend within the libavfilter/dnn_backend_tf.c source file. The issue occurs in

FFmpeg's TensorFlow backend has a bug where a task object gets freed twice in certain error situations, causing a double-free condition (a memory safety error where the same memory is released multiple times). This can crash FFmpeg or programs using it when processing TensorFlow-based DNN models (deep neural network models), resulting in a denial-of-service attack, but it does not allow attackers to run arbitrary code.
