Kernel memory read and write via untrusted pointer
Published Sep 21, 2026 · Updated Sep 21, 2026
Untrusted pointer dereference in Colorful iGame Center 1.0.3.4 allows local users to read and write arbitrary kernel memory via an IOCTL. The ene.sys IOCTL handler function sub_140001AF0 converts an attacker-controlled value into a pointer and dereferences it without validation. Low privileges and local access are required; successful exploitation crosses into kernel memory and can compromise confidentiality, integrity, and availability.
