From H.266 (V3) (09/2023) p. 321: It is a requirement of bitstream conformance that the luma block vector bvL shall obey the following constraints: - CtbSizeY is greater than or equal to ((yCb + (bvL[ 1 ] >> 4)) & (CtbSizeY − 1)) + cbHeight This patch checks this is true, which fixes crashes on fuzzed bitstreams.
