CVE-2026-105839

libmikmod before 3.3.14 contains an integer overflow in the Oktalyzer loader OKT_doPBOD() that allows attackers to cause heap buffer overflow via crafted track counts. Attackers can supply an OKT module whose SLEN chunk wraps the 16-bit numtrk value, causing PBOD writes past allocated track pointers for crashes or code execution.
