CVE-2022-50798Public exploit

Application crash via oversized channel count

Published Dec 30, 2025 · Updated Dec 30, 2025

Division by zero in SoX 14.4.2 allows attackers to crash the application by converting a crafted SND file to WAV. During WAV header writing, wavwritehdr accepts a channel count above 65,535, truncates it into the 16-bit block-alignment field, and divides by the resulting zero value. CVE-2022-50798 is rejected as a duplicate of CVE-2017-11359; exploitation requires the crafted file to be processed, and the bounded consequence is an application crash.
