Fraunhofer HHI VVdeC through 3.2.1 contains a NULL pointer dereference vulnerability in InterPrediction::xPredInterBlk that allows attackers to crash the decoder by switching SPS to enable reference wrap-around. Attackers can supply a crafted VVC bitstream activating a new SPS with sps_ref_wraparound_enabled_flag set, causing reads from missing PIC_RECON_WRAP buffers and denial of service.
