Realtek Waves MaxxAudio driver 1.6.2.0, as used on Dell laptops, installs with incorrect file permissions. As a result, a local attacker can escalate to SYSTEM.

WavesSysSvc in Waves MAXX Audio allows privilege escalation because the General registry key has Full Control access for the Users group, leading to DLL side loading. This affects WavesSysSvc64.exe 1.9.29.0.
