Audio disruption via incorrect _sx bounds check
Published Oct 21, 2024 · Updated May 23, 2026
Improper bounds checking in Linux kernel ASoC _sx controls allows local users to disrupt audio through out-of-range control values. snd_soc_put_volsw_sx() treats the _sx max field like an absolute value even though it represents a step count, permitting an incorrect upper-bound comparison. Low-privilege local access to an affected ASoC control is required, and public records describe no consequence beyond availability loss.
