CVE-2026-46179

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture (ALSA) System on Chip (ASoC) Sound Open Firmware (SOF) subsystem. This vulnerability occurs when reporting the pointer for a compressed stream, where the I/O frame position is divided by values that can be zero if the stream parameters are unconfigured. An attacker could potentially trigger a divide-by-zero error, leading to a system crash and a denial of service.
