MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires an attacker to hold a high-privileged account (e.g., administrator or root) with an active local logon session on the physical or virtual host where Oracle VM VirtualBox 7.2.6 is installed and running. The attack cannot be performed remotely - AV:L confirms physical or logical local access is mandatory. No user interaction from a separate user is required (UI:N). The scope does not change (S:U), so a successful attacker cannot leverage this to compromise the underlying host OS or adjacent VMs. Exploitation is bounded to partial availability disruption only; there is no path to information disclosure or data modification. The primary limiting factor is the combination of required local access and high-privilege prerequisite, which dramatically reduces the population of potential attackers to insiders or already-compromised privileged accounts. |
| Impact | All available signals consistently indicate very low real-world risk. The CVSS base score of 2.3 is one of the lowest possible meaningful scores, driven by AV:L (local-only), PR:H (high privileges), and A:L (partial, not complete, availability impact). EPSS corroborates this at 0.01% probability of exploitation within 30 days (2nd percentile globally). SSVC classification is Exploitation: none, Automatable: no, Technical Impact: partial - affirming this is not a candidate for emergency remediation. CISA KEV listing is absent and no POC has been identified. The 'Authentication Bypass' tag in the source intelligence is discordant with the CVSS vector (PR:H requires high-privileged access by definition) and the description (which explicitly states 'high privileged attacker'); this tag may be a mis-categorization or metadata artifact and should not be treated as confirmed. The vulnerability should be treated as a routine low-severity item, addressable via normal patch cycle rather than emergency response. |
| Exploit ScenarioDerived | An administrator or operator account already authenticated to the host operating system invokes a crafted operation against the VirtualBox Core component, causing the hypervisor to enter a degraded state and partially losing availability for running guest VMs. No public proof-of-concept code has been identified at time of analysis. Because attack complexity is low (AC:L), a skilled local attacker with the required privileges could reliably trigger the condition without trial-and-error. |

Alert meAnalysisAIv1 – Jul 24, 2026
Partial denial-of-service in Oracle VM VirtualBox 7.2.6 Core component allows a locally authenticated, high-privileged attacker to degrade availability of the hypervisor. Exploitation is limited to the local system and requires pre-existing administrative-level access, with no confidentiality or integrity impact. No public exploit code has been identified and CISA has not listed this in the Known Exploited Vulnerabilities catalog; EPSS at 0.01% (2nd percentile) reflects near-zero exploitation probability.
RemediationAI
Consult Oracle's Critical Patch Update for April 2026 at https://www.oracle.com/security-alerts/cpuapr2026.html to obtain the patched VirtualBox release; Oracle typically provides an updated build within the same minor version line (7.2.x). No exact fix version number is independently confirmed beyond the advisory reference, so obtain the specific patched binary directly from Oracle's download portal or package repositories. Given the low CVSS score, high privilege requirement, and local-only attack vector, the practical compensating control is ensuring that only trusted, authorized administrators have logon access to hosts running VirtualBox - restricting local host access limits exposure entirely, with no meaningful operational trade-off. There is no requirement to disable the product or restrict network access, as the attack vector is local.

Technical ContextAI · show details
Oracle VM VirtualBox is a cross-platform type-2 hypervisor; the Core component handles VM lifecycle, device emulation, and privilege separation between guest and host. CWE-284 (Improper Access Control) indicates the root cause is insufficient enforcement of access boundaries within the Core subsystem - a privileged local user can invoke functionality in a way that triggers a partial availability disruption (e.g., service hang, resource exhaustion, or crash) without crossing confidentiality or integrity boundaries. The CPE string (cpe:2.3:a:oracle_corporation:oracle_vm_virtualbox:*:*:*:*:*:*:*:*) is intentionally broad, but Oracle's advisory and EUVD data confirm scope is limited to version 7.2.6 specifically. Scope is unchanged (S:U), meaning exploitation cannot pivot from the VirtualBox process to the underlying host OS or adjacent VMs.
