This vulnerability can lead to a Denial of Service (DoS) because the driver fails to check the return status of runtime power management (PM) resume operations before accessing hardware registers. A local attacker could exploit this flaw during audio format configuration to trigger register accesses while the device is unpowered, resulting in system instability or a kernel crash.
