IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to execute arbitrary code due to an out-of-bounds read.
AnalysisAI
Local arbitrary code execution in IBM AIX 7.2 and 7.3, and IBM PowerVM VIOS 4.1, stems from an out-of-bounds read (CWE-125) exploitable by a low-privileged local user with no user interaction required. A successful attacker achieves full confidentiality, integrity, and availability compromise of the affected system, as reflected in the CVSS 3.1 score of 7.8 (High) with AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing local account on the affected IBM AIX 7.2/7.3 or PowerVM VIOS 4.1 system with at minimum low-level (non-root) privileges, as confirmed by PR:L in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.8 (High) accurately captures the severity of the impact - full C/I/A compromise - while the local attack vector (AV:L) and low privilege requirement (PR:L) constrain the realistic attacker population to those who already hold a local foothold. … 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 | Organizations should consult the IBM security advisory at https://www.ibm.com/support/pages/node/7283858 for official fix levels and interim fixes for IBM AIX 7.2, AIX 7.3, and PowerVM VIOS 4.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
