Summary

[none]

Details

An incomplete fix for CVE-2024-47778 allows an out-of-bounds read in gstwavparseadtlchunk() function. The patch added a size validation check lsize + 8 > size, but it does not account for the GSTROUNDUP2(lsize) used in the actual offset calculation. When lsize is an odd number, the parser advances more bytes than validated, causing OOB read.
