Received Received - Intake

Use-After-Free in GPU DDK Kernel Module

Publication date: 2026-11-13

Last updated on: 2026-11-13

Assigner: imaginationtech

Description
Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot. The weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.

CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability involves improper GPU system calls made by software running as a non-privileged user through the DDK kernel module interface. When the interface is used unsafely, a use-after-free condition can occur, leading to kernel memory corruption, system instability, or unexpected reboots.

Detection Guidance

This vulnerability involves improper GPU system calls and a use-after-free condition in the DDK kernel module. Detection requires checking for kernel memory corruption or system instability caused by unsupported GPU driver usage. Monitor system logs for crashes, reboots, or GPU-related errors. Use commands like 'dmesg | grep -i error' or 'journalctl -k | grep -i gpu' to identify kernel issues. Ensure GPU drivers are updated and only supported interfaces are used.

Impact Analysis

The vulnerability may cause kernel memory corruption, leading to system crashes, instability, or forced reboots. It could also allow unintended operations if exploited, potentially compromising system integrity or availability.

Compliance Impact

This vulnerability could lead to kernel memory corruption or system instability, potentially causing unauthorized data access or system failures. Such issues may violate compliance requirements under GDPR (data protection) or HIPAA (health data security) by compromising data integrity or availability.

Mitigation Strategies

Update GPU drivers to the latest version from the vendor to ensure the DDK kernel module interface is patched against improper system calls and use-after-free conditions.
