CVE-2026-112012 Details
Description
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.
A stack-based buffer underflow vulnerability has been identified in libtta, a True Audio codec library, in versions through 2.3. The issue arises in the functions tta_decoder_process_stream() and tta_decoder_process_frame(). The vulnerability is caused by insufficient validation of the channel count in the TTA file header, allowing attackers to craft files that declare zero channels. This oversight leads to a decorrelation process that accesses memory out-of-bounds, specifically cache[-1], using values derived from the audio stream. As a result, stack memory is corrupted in applications that utilize this decoding library.
Users are advised to update to version 2.3 or later, where this vulnerability has been addressed.
