Horizon Alert
Summary of the vulnerability and why it matters
The Arm Mali GPU kernel driver is vulnerable due to improper handling of GPU memory operations, which can lead to a use-after-free condition. This flaw can enable privilege escalation or the disclosure of sensitive information. The potential business impact includes unauthorized access to data and compromised system integrity.
- Vulnerable component: Arm Mali GPU kernel driver
- Core weakness: GPU memory mishandling
- Main business impact: Privilege escalation, information disclosure
Attack Path
How an attacker could exploit the issue
A vulnerability in the Arm Mali GPU kernel driver could allow an attacker to gain elevated privileges or access sensitive information. This occurs when GPU memory operations are mishandled, resulting in a use-after-free condition. Such a vulnerability can impact affected organizations by potentially compromising system integrity and confidentiality.
- Requires local access.
- Attacker exploits memory handling.
- Results in privilege escalation or data disclosure.
Live Threat
Current exploitation, exposure, and threat context
