ultrahdr: compress image reads outside bounds for non aligned widths jpeg_write_raw_data() processes one MCU row per call, and thus one must pass buffer of at least max_v_samp_factor * DCTSIZE scanlines. The buffer must be large enough to hold the actual data plus padding to DCT-block boundaries. Bug: 284117683 Test: ./ultrahdr_enc_fuzzer Change-Id: I993773817bf3805463bb21bb977624d6c2d45a0b
