CVE-2024-38812 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2024-38812?

Affected package information for CVE-2024-38812 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2024-38812?

Apply the vmware cloud foundation security patch or hotfix for CVE-2024-38812 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2024-38812 across my infrastructure?

Inventory every vmware cloud foundation deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2024-38812 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2024-38812?

O3 detects and blocks CVE-2024-38812 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2024-38812 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2024-38812, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-38812?

CVE-2024-38812 has an EPSS (Exploit Prediction Scoring System) score of 54.1%, placing it in the 99th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2024-38812 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2024-38812 (VMware vCenter Server Heap-Based Buffer Overflow Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2024-11-20. CISA required all US federal civilian agencies to remediate this vulnerability by 2024-12-11. The required action was: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2024-38812?

CVE-2024-38812 is classified as CWE-122 (CWE-122), Out-of-bounds Write (CWE-787). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Which products and versions are affected by CVE-2024-38812?

CVE-2024-38812 affects vmware cloud foundation; vmware vcenter server (2 versions, e.g. 7.0, 8.0). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2024-38812 published, and has it been updated?

CVE-2024-38812 was published on September 17, 2024 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
