Why it matters

The Linux kernel vulnerability in ASoC SOF ipc4-pcm requires defenders to assess exposure and prioritize verification of Linux kernel versions and deployments.

• Verify Linux kernel versions and ASoC SOF ipc4-pcm component usage
• Assess pipeline state change handling in IPC timeout or firmware crash scenarios

Technical summary

The Linux kernel ASoC SOF ipc4-pcm component has a vulnerability related to handling pipeline state changes in case of IPC timeout or firmware crash. The kernel needs to continue the pipeline trigger to correctly reset its internal state. This vulnerability requires defenders to assess exposure and prioritize verification of Linux kernel versions and deployments using the ASoC SOF ipc4-pcm component. The vulnerability has been resolved in the Linux kernel, and defenders should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. The Linux kernel versions and ASoC SOF ipc4-pcm component usage should be verified, and pipeline state change handling in IPC

Defensive priority

Defenders should assess exposure and prioritize verification of Linux kernel versions and deployments using the ASoC SOF ipc4-pcm component.

Recommended defensive actions

• Assess Linux kernel versions and ASoC SOF ipc4-pcm component usage
• Verify pipeline state change handling in IPC timeout or firmware crash scenarios
• Review Linux kernel updates and patches for ASoC SOF ipc4-pcm
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but evidence is limited. Official sources indicate a fix has been applied to the Linux kernel. The vulnerability has been resolved in the Linux kernel, and defenders should assess exposure and prioritize verification of Linux kernel versions and deployments using the ASoC SOF ipc4-pcm component. The Linux kernel versions and ASoC SOF ipc4-pcm component usage should be verified, and pipeline state change handling in IPC timeout or firmware crash scenarios should be
