Assigner: imaginationtech

Description

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause OOB read kernel memory access and in certain cases cause GPU UAF of arbitrary pages. Incorrect validation of array index can lead to OOB read and potentially to GPU UAF of arbitrary pages.

CWE-823	The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.

Attack-Flow Graph

Executive Summary

This vulnerability involves software running as a non-privileged user making improper GPU system calls. This can lead to an out-of-bounds (OOB) read of kernel memory. In some cases, it may also result in a GPU use-after-free (UAF) condition affecting arbitrary pages.

Detection Guidance

Detection of this vulnerability requires checking for improper GPU system calls or memory access issues. Monitor kernel logs for OOB read errors or GPU UAF events. Use system monitoring tools like dmesg or journalctl to inspect GPU-related errors. Ensure GPU drivers are updated to the latest version to mitigate risks.

Impact Analysis

An attacker could exploit this to read sensitive kernel memory or cause system instability. This might lead to unauthorized data access, crashes, or privilege escalation if combined with other vulnerabilities.

Compliance Impact

This vulnerability involves improper GPU system calls leading to out-of-bounds (OOB) read kernel memory access and potential GPU use-after-free (UAF) of arbitrary pages. Such memory corruption issues could compromise system integrity, potentially exposing sensitive data or enabling unauthorized access, which may violate compliance requirements under GDPR or HIPAA depending on the affected system and data.

Mitigation Strategies

Update GPU drivers to the latest version from the vendor to address the improper validation of array index and OOB read issues.
