AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local access with a low-privilege account required (AV:L, PR:L); no complexity or interaction constraints; full confidentiality, integrity, and availability impact consistent with privilege escalation to root.

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to gain elevated privileges due to improper privilege management.
AnalysisAI
Local privilege escalation in IBM AIX 7.2 and 7.3, and IBM PowerVM VIOS 4.1 allows a low-privileged local user to gain elevated-likely root-level-access through improper privilege management (CWE-269). The CVSS 3.1 score of 7.8 (AV:L/AC:L/PR:L/UI:N) reflects low-complexity exploitation requiring only a standard local account with no user interaction. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing local account on the affected IBM AIX 7.2, AIX 7.3, or PowerVM VIOS 4.1 system with at minimum low-privilege access (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 score and AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H vector indicate a straightforward local privilege escalation requiring no special conditions beyond a low-privilege account. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch is available from IBM. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems running IBM AIX 7.2, 7.3, or PowerVM VIOS 4.1 and assess which are connected to production workloads or sensitive data. …
