CVE-2026-112011

libtta through 2.3 contains an integer overflow vulnerability in tta_decoder_init_get_info() that allows attackers to cause a heap buffer overflow on 32-bit builds via unvalidated header fields. Attackers can supply a crafted .tta file with a sample rate of 1 and large samples value, wrapping the seek table allocation and crashing applications.
