IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary code due to a buffer overflow.
AnalysisAI
Remote code execution in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 stems from a buffer overflow (out-of-bounds write) that a remote attacker can trigger without authentication or user interaction, yielding full compromise of the affected system. IBM PSIRT rates it CVSS 9.8, reflecting complete confidentiality, integrity, and availability loss. …

Vulnerability AssessmentAI
| Exploitation | Per the CVSS vector (AV:N/AC:L/PR:N/UI:N), no special conditions - remote unauthenticated exploitation with no user interaction against IBM AIX 7.2/7.3 or PowerVM VIOS 4.1. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, score 9.8) describes a worst-case profile: network-reachable, low complexity, no privileges, no user interaction, with full CIA impact - the kind of pre-auth RCE that warrants urgent patching where the product is exposed. … 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 | Patch available per vendor advisory: apply the IBM-provided fixes (iFix/APAR filesets) documented at https://www.ibm.com/support/pages/node/7283858 for AIX 7.2, AIX 7.3, and VIOS 4.1 - the input does not include an exact fix fileset/version, so pull the precise patched level directly from that bulletin. … 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 their network accessibility and criticality to business operations. …
