CVE-2024-11614
CVE-2024-11614: Out-of-bounds read vulnerability in DPDK Vhost library allows crashing hypervisor's vSwitch. A compromised guest can forge Virtio descriptors leading to out-of-bounds reads, causing a denial of service. This flaw enables an attacker controlling a malicious VM with a virtio driver to crash the vhost-user side by sending a crafted packet with a Tx checksum offload request and an invalid csum_start offset. While the CVSS score is 7.4, the SOCRadar Vulnerability Risk Score (SVRS) is 30, indicating a relatively lower immediate risk compared to critical vulnerabilities. However, the "In The Wild" tag suggests potential exploitation. This issue could destabilize virtualized environments and disrupt network services. Organizations using DPDK's Vhost library should apply necessary patches to prevent potential attacks.
Description
CVE-2024-11614 is an out-of-bounds read vulnerability in the Vhost library checksum offload feature of DPDK. This vulnerability could allow a malicious guest virtual machine (VM) to crash the hypervisor's vSwitch by manipulating Virtio descriptors, causing the vhost-user side to read outside of allocated memory. This is a serious vulnerability that can result in denial of service attacks and potentially lead to further system compromise.
While the CVSS score is 7.4, the SOCRadar Vulnerability Risk Score (SVRS) for this vulnerability is 30, indicating a moderate risk level. This discrepancy is due to the SVRS incorporating additional factors like threat actor activity, exploit availability, and real-world impact, which the CVSS does not consider.
Key Insights
- Exploitable by Untrusted Guests: This vulnerability allows malicious guests to exploit the hypervisor's vSwitch, potentially leading to denial-of-service attacks and other security breaches.
- Potential for System Compromise: While the primary impact is a denial-of-service, this vulnerability can create opportunities for attackers to gain further access to the system.
- Limited Public Information: There are currently no known threat actors actively exploiting CVE-2024-11614, and no active exploits have been publicly reported. However, the vulnerability's nature poses a significant risk.
Mitigation Strategies
- Patching: Implement the latest security patches for DPDK to address this vulnerability. This is the most critical step in mitigating this vulnerability.
- Virtualization Security: Employ robust security measures for virtualized environments. This includes strong password policies, network segmentation, and appropriate isolation techniques for guest VMs.
- Vulnerability Monitoring: Implement tools to monitor for potential exploits related to CVE-2024-11614 and other vulnerabilities.
- Security Awareness: Train users to be vigilant against malicious activity and to report suspicious behavior.
