Kernel-address disclosure via system-information IOCTL
Published Mar 15, 2024 · Updated Apr 10, 2025
Information disclosure in Zemana AntiLogger 2.74.204.664 allows local users to read the Windows kernel base address through a driver IOCTL. The 0x80002020 handlers in zam64.sys and zamguard64.sys return ZwQuerySystemInformation module data directly to the caller. A low-privileged process must first authorize its current process ID with IOCTL 0x80002010; the leak defeats kernel ASLR.
