Kernel Driver Privilege Escalation via IOCTL Memory Manipulation

A vulnerability was found in Colorful iGameCenter 2.0.0.81. This vulnerability affects the function sub_11504 in the library WinRing0x64.sys of the component IOCTL Dispatch. Performing a manipulation of the argument PhysicalAddress/AlignNumer/AlignSize results in improper privilege management. Attacking locally is a requirement.

Casky was already ahead

This CVE exploits attack patterns that Casky's 224matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-82628 represents a critical privilege escalation vulnerability in Colorful iGameCenter 2.0.0.81, specifically within the WinRing0x64.sys kernel driver's IOCTL dispatch handler. By manipulating memory addressing parameters (PhysicalAddress, AlignNumer, AlignSize) passed to the sub_11504 function, an authenticated local attacker can bypass privilege boundaries and execute arbitrary code with kernel-level access. This vulnerability is particularly concerning because kernel drivers with direct hardware access are trusted system components, making this a gateway for complete system compromise. Organizations deploying iGameCenter—commonly used in gaming and performance monitoring contexts—face significant risk, especially in environments where users have local execution capabilities or where the software is deployed on multi-tenant systems.

Casky's 224 matched skills, powered by Claude's extended reasoning capabilities, detect this attack pattern by mapping to MITRE ATT&CK Technique TA0004 (Privilege Escalation) and correlating CWE-266/CWE-269 (improper privilege management indicators). Practitioners using Casky would observe detection patterns focused on: abnormal IOCTL calls to WinRing0x64.sys with malformed memory parameters, suspicious kernel-mode code execution following low-privilege process interactions with the driver, and privilege boundary crossing without corresponding authorization events. The platform's skill correlation would highlight the progression from local code execution to kernel access, helping teams identify exploitation attempts before privilege escalation completes. Key findings would emphasize driver loading behavior, memory mapping anomalies, and the absence of corresponding security policy enforcement—critical indicators that distinguish this attack from legitimate driver operations.
