Horizon Alert
Summary of the vulnerability and why it matters
The Arm Mali GPU Kernel Driver is susceptible to a memory leak vulnerability. This flaw permits an unauthorized user to execute standard GPU operations that can expose sensitive information from the system's kernel. This could lead to unauthorized access to internal system data.
- Vulnerable component: Arm Mali GPU Kernel Driver
- Core weakness: Memory leak exposes kernel metadata
- Main business impact: Unauthorized access to sensitive data
Attack Path
How an attacker could exploit the issue
A memory leak vulnerability exists in the Mali GPU Kernel Driver. This issue allows a local, non-privileged user to perform specific GPU operations. These operations can expose sensitive information from the system's kernel metadata.
- Local access to the device is required.
- Attacker triggers a GPU processing operation.
- Sensitive kernel metadata is exposed.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability allows a non-privileged user to access sensitive kernel metadata through GPU processing operations. The impact is an information disclosure, where kernel metadata could be exposed. The exploitability is classified as internal, meaning it requires local access to the affected system.
- Likely attacker skill level: Low.
- Required access or conditions: Local, non-privileged user access.
- Business risk or urgency: Low.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability impacts organizations utilizing Arm's Mali GPU Kernel Driver. Successful exploitation could allow a local, non-privileged user to access sensitive kernel metadata, posing a risk to data confidentiality. The vulnerability has been documented and is considered to have low severity, but its presence on the Known Exploited Vulnerabilities catalog warrants attention.
- Identify affected systems with the specified GPU drivers.
- Isolate or restrict access to vulnerable systems.
- Apply vendor updates, verify fixes, and monitor systems.
