CVE-2022-41894

CVE-2022-41894 affects TensorFlow/TFLite CONV_3D_TRANSPOSE reference kernel. The bug increments data_ptr by num_channels instead of output_num_channels, enabling an out-of-bounds write to the bias buffer when input channels exceed output channels. Attack requires using the reference kernel resolv...
