CVE-2024-27057

Audio resume failure via interrupted pipeline reset

Published May 1, 2024 · Updated May 11, 2026

Denial of service in the Linux kernel allows local users to prevent audio from resuming after a Sound Open Firmware DSP crash during suspend. sof_ipc4_pcm_hw_free() requests a forced reset through sof_ipc4_set_multi_pipeline_state(), but an IPC error interrupts the transition and leaves kernel pipeline state inconsistent with rebooted firmware. Reachability requires IPC4 SOF audio to be active during suspend and a DSP crash or reset failure; the consequence is limited to audio resume failure until a subsequent DSP boot corrects the state.
