Local access and high privileges required to reach the kernel driver IOCTL; only low confidentiality impact as physical memory read scope is bounded by attacker knowledge.

A flaw has been found in Chengdu Qilu Technology Ludashi 6.1026.4715.714. The affected element is the function sub_11008 in the library ComputerZ_x64.sys. Executing a manipulation of the argument PhysicalAddress can lead to information disclosure. The attack needs to be launched locally. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Information disclosure in Chengdu Qilu Technology Ludashi 6.1026.4715.714 allows a local high-privileged attacker to read arbitrary physical memory by sending a crafted IOCTL with a manipulated PhysicalAddress argument to the kernel driver ComputerZ_x64.sys. The vulnerable function sub_11008 exposes physical memory read capability to user-mode callers without adequate address validation, a classic pattern in poorly designed Windows kernel drivers that can expose sensitive in-memory data such as credentials or cryptographic material. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) local access to a 64-bit Windows machine with Ludashi 6.1026.4715.714 installed and ComputerZ_x64.sys loaded; (2) high-privilege (administrator-level) access to open a handle to the kernel driver and send IOCTLs - PR:H per the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 1.8 (AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N) is low, and the metrics are well-calibrated: exploitation requires local access with high privileges (PR:H), limiting the attacker population to those already holding administrative rights on the machine. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch is available at time of analysis; the vendor did not respond to disclosure per the VulDB report. … Detailed patch versions, workarounds, and compensating controls in full report. |
