Description
Kernel-mode drivers are drivers that operate in kernel mode. Kernel mode allows virtually unlimited access to hardware and memory. A poorly written kernel driver may cause system instability and data corruption. Malicious code inserted in a kernel-mode driver has almost no limit on what it may do. Most modern printers do not require kernel-mode drivers.
