Change KVM permission to 0664

[ryanw-mobile]

🛑 Security Vulnerability: KVM permissions are set to world-writable (0666) which creates a security risk. This allows any user on the system to access the KVM device, potentially enabling privilege escalation or unauthorized access to virtualization features.

Suggested change
          echo 'KERNEL=="kvm", GROUP="kvm", MODE="0666", OPTIONS+="static_node=kvm"' | sudo tee /etc/udev/rules.d/99-kvm4all.rules
          echo 'KERNEL=="kvm", GROUP="kvm", MODE="0664", OPTIONS+="static_node=kvm"' | sudo tee /etc/udev/rules.d/99-kvm4all.rules
