Description

CVE-2024-47895 describes a vulnerability in kernel software running within a Guest VM. This vulnerability arises when the kernel software posts improper commands to the GPU Firmware, allowing potential access to data outside the virtualized GPU memory of the Guest VM. This vulnerability could be exploited by malicious actors to gain unauthorized access to sensitive data within the Guest VM.

Key Insights

• Potential for Data Exfiltration: The improper commands sent to the GPU firmware could allow attackers to read data outside the Guest VM's virtualized GPU memory. This presents a significant risk for data exfiltration, particularly if sensitive information is stored in the Guest VM's memory.
• Exploitation in Virtualized Environments: This vulnerability is particularly relevant for organizations running virtualized environments. It highlights the importance of securing not only the host system but also the Guest VMs, as vulnerabilities in the kernel software within the Guest VM can pose a significant risk.
• Potential for Privilege Escalation: While the initial focus might be on data exfiltration, attackers could leverage this vulnerability to gain elevated privileges within the Guest VM. This could lead to further compromise of the virtualized environment.
• SVRS Ranking: Despite a CVSS score of 0, the SOCRadar Vulnerability Risk Score (SVRS) stands at 34, indicating a moderate level of risk. This highlights the importance of assessing vulnerabilities beyond traditional scoring systems, considering factors like potential for data exfiltration and exploitability in real-world scenarios.

Mitigation Strategies

• Patching Kernel Software: Prioritize patching the kernel software in both the host and Guest VM to address the vulnerability. Regularly update the kernel software to ensure that any known vulnerabilities are patched.
• Security Hardening: Implement security hardening measures for the Guest VM, including restricting access to sensitive data, limiting network connections, and utilizing a strong password policy.
• Monitoring and Intrusion Detection: Implement security monitoring tools and intrusion detection systems to detect suspicious activity and identify potential attempts to exploit the vulnerability.
• Security Awareness Training: Educate users about the risks posed by this vulnerability and reinforce best practices for data security and user accountability.
