Description
An incomplete fix for CVE-2024-47778 allows an out-of-bounds read in gst_wavparse_adtl_chunk() function. The patch added a size validation check lsize + 8 > size, but it does not account for the GST_ROUND_UP_2(lsize) used in the actual offset calculation. When lsize is an odd number, the parser advances more bytes than validated, causing OOB read.
