Improper GPU Driver IOCTL Allocation Leading to Double Free

Publication date: 2026-09-04

Last updated on: 2026-09-04

Assigner: imaginationtech

Description
Software installed and run as a non-privileged user may conduct improper GPU driver IOCTL calls to create an allocation scenario that when freed would cause double free and kernel heap corruption. Scenario caused by fabricating a specific combination of flags on the allocation interface that would cause an incorrect double free event when freed.

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 driver IOCTL calls made by software running as a non-privileged user. The issue occurs when specific flag combinations on the allocation interface cause an incorrect double free event during memory deallocation, leading to kernel heap corruption.

Impact Analysis

This vulnerability could allow an attacker with local access to cause system instability, crashes, or potentially execute arbitrary code in the kernel. It may lead to denial of service or privilege escalation if exploited successfully.

Compliance Impact

This vulnerability involves kernel heap corruption and double free errors due to improper GPU driver IOCTL calls, which could lead to system instability or crashes. Such flaws may compromise data integrity and availability, potentially violating compliance requirements for GDPR (data protection) and HIPAA (health data security) if exploited.

Mitigation Strategies

Update GPU drivers to the latest version provided by the vendor to patch the improper IOCTL handling. Restrict non-privileged users from executing GPU-related operations if possible. Monitor system logs for unusual kernel heap corruption events or double free errors.
