SeLoadDriverPrivilege is a Windows user right that allows a process to load or unload device drivers. Because drivers run in kernel mode, this privilege can grant extremely powerful access to memory, files, the registry, and security controls. Microsoft treats it as highly sensitive because a loaded driver can act with far more authority than a normal user process.
In cyber attacks, this right matters when an attacker has already reached local administrative or equivalent access and wants to extend control into the kernel. With SeLoadDriverPrivilege, a trusted signed driver can sometimes be loaded and then abused for stealth, tampering, or protection bypass. Defenders reduce this risk by tightly limiting which accounts hold the privilege, monitoring driver-load events, and using code integrity controls such as WDAC to restrict untrusted or unexpected drivers. It is a classic example of a legitimate administration right becoming a post-compromise weapon.
