CVE-2026-97407

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: rockchip: rockchip_pdm: Handle runtime PM resume failures in set_fmt

rockchip_pdm_set_fmt() calls pm_runtime_get_sync() before accessing

hardware registers, but ignores its return value.

If the runtime resume fails, the function continues to perform register

accesses while the device state is undefined.

Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() and

return early on failure to avoid unpowered register accesses.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
