CVE-2026-112012 · libtta through 2.3 Stack Out-of-Bounds Write via Zero Channel Count
This page contains facts from public vulnerability sources. Check the original advisory before updating.
libtta through 2.3 contains a stack out-of-bounds read and write vulnerability in tta_decoder_process_stream() and tta_decoder_process_frame() because header checks never reject a zero channel count. Attackers can supply a crafted .tta file declaring zero channels so decorrelation accesses cache[-1] with stream-derived values, corrupting stack memory in decoding applications.
