Overview

CVE-2025-67246 is a high-severity vulnerability. It was published on January 15, 2026 and has a CVSS 3.1 base score of 7.3 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.3, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

A local information disclosure vulnerability exists in the Ludashi driver before 5.1025 due to a lack of access control in the IOCTL handler. This driver exposes a device interface accessible to a normal user and handles attacker-controlled structures containing the lower 4GB of physical addresses. The handler maps arbitrary physical memory via MmMapIoSpace and copies data back to user mode without verifying the caller's privileges or the target address range. This allows unprivileged users to read arbitrary physical memory, potentially exposing kernel data structures, kernel pointers, security tokens, and other sensitive information. This vulnerability can be further exploited to bypass the Kernel Address Space Layout Rules (KASLR) and achieve local privilege escalation.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
