CVE-2025-37889

Local service interruption via mis-scaled volume limits

Published May 9, 2025 · Updated May 23, 2026

Range-check error in Linux kernel ASoC mixer controls allows local users to interrupt service through crafted volume values. snd_soc_put_volsw adds the hardware minimum before comparing a user-supplied control value with platform_max, while snd_soc_info_volsw_range subtracts that minimum when reporting the limit. Published v3 scoring bounds the effect to availability, and reachability requires low-privilege local access plus an affected ASoC control.
