Horizon Alert
Summary of the vulnerability and why it matters
The Arm GPU kernel drivers contain a vulnerability related to improper memory processing. This flaw can allow a local user to access memory that has already been freed. Such access could potentially lead to unauthorized information disclosure or system compromise. The impact on affected organizations could include the loss of sensitive data and disruption of critical operations.
- Vulnerable Arm GPU kernel drivers
- Improper GPU memory processing
- Potential data exposure or system compromise
Attack Path
How an attacker could exploit the issue
This vulnerability allows a local, unprivileged user to access freed memory by performing improper GPU memory processing operations. The attack leverages a flaw in the GPU kernel driver to gain unauthorized access to already released memory locations. This could lead to a compromise of system integrity and data confidentiality.
- Local, unprivileged user access
- Improper GPU memory operations
- Gain access to freed memory
Live Threat

Operational Fix
Recommended remediation, mitigation, and detection steps
A vulnerability in Arm's GPU kernel drivers could allow a local user to access freed memory, potentially leading to unauthorized data access or modification. This could impact the confidentiality and integrity of data processed by affected systems. The vulnerability requires local access, meaning an attacker must already have some level of access to the system.
- Identify affected systems and GPU kernel drivers.
- Reduce exposure or isolate affected systems.
- Apply vendor fixes, verify implementation, and monitor.
