A high-severity use-after-free vulnerability has been identified in the Arm Bifrost and Valhall GPU Kernel Drivers. This vulnerability allows local, non-privileged users to make improper GPU memory processing operations to gain access to already freed memory. The CVSS score of 7.8 highlights the urgent need for organizations to address this flaw. The impact of such vulnerabilities can lead to significant security risks, including unauthorized access to sensitive information.
Organizations should prioritize patching immediately, especially given the local attack vector and low privileges required. The vulnerability affects versions from r34p0 through r40p0 of both the Bifrost and Valhall GPU Kernel Drivers. Consequently, it is crucial for users of these drivers to take immediate action to mitigate potential risks.
The vulnerability has been flagged in the Known Exploited Vulnerabilities (KEV) catalog, indicating a recognized threat that organizations must monitor closely. Security teams should ensure their systems are updated with the latest patches to prevent exploitation.
As the exploitation status is currently high, organizations are urged to assess their environments for the presence of these vulnerable drivers and implement necessary patches or workarounds as soon as possible.
Vulnerability Details
The vulnerability identified as CVE-2024-4610 is classified under the Common Weakness Enumeration (CWE) as CWE-416 – Use After Free. It affects the Arm Bifrost and Valhall GPU Kernel Drivers, allowing local users to manipulate GPU memory processing operations improperly.
Published on June 7, 2024, this vulnerability carries a CVSS score of 7.8, indicating a high severity. The attack vector is local, with low complexity and low privileges required, while user interaction is not necessary. The impacts on confidentiality, integrity, and availability are all rated as high.
The affected versions include Bifrost GPU Kernel Driver from r34p0 through r40p0 and Valhall GPU Kernel Driver from r34p0 through r40p0. Organizations using these drivers should take immediate measures to update or mitigate the risk.
Technical Analysis
The root cause of this vulnerability lies in improper GPU memory management, specifically a use-after-free condition that can be exploited by a local attacker. The attack vector is local; thus, the attacker must have access to the system where the vulnerable drivers are installed.
The attack complexity is classified as low, indicating that it does not require sophisticated techniques to exploit. Only low privileges are necessary, which makes this vulnerability particularly concerning for environments where multiple users may have access.
User interaction is not required for exploitation, heightening the risk as it can be executed without any action from the target user. The vulnerability has high impacts on confidentiality, integrity, and availability, making it critical for organizations to address.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-4610 is significant. The potential for local users to exploit this vulnerability could lead to unauthorized access to sensitive data or system resources. Organizations relying on the affected GPU drivers must understand that the blast radius could encompass critical components of their infrastructure.
Given the high CVSS score of 7.8 and its presence in the KEV catalog, organizations should assess their urgency in addressing this vulnerability. The potential for exploitation is non-trivial, and thus, security teams must prioritize remediation efforts.
