AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Network-reachable service processes attacker pointers with no auth or interaction and low complexity, yielding full code execution, hence AV:N/AC:L/PR:N/UI:N and C/I/A:H.

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary code due to improper validation of network-supplied pointers.
AnalysisAI
Remote code execution in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 lets an unauthenticated network attacker run arbitrary code by supplying malicious pointers that the OS fails to validate (CWE-843 type confusion). The flaw carries a critical CVSS 9.8 and was disclosed by IBM PSIRT with no user interaction required, but there is no public exploit identified at time of analysis and it is not listed in CISA KEV. …

Vulnerability AssessmentAI
| Exploitation | The prerequisite is network reachability to the vulnerable AIX/VIOS network service that processes the untrusted pointer input; per the CVSS vector (AV:N/AC:L/PR:N/UI:N) there is no authentication, no user interaction, and low complexity required, so exploitation works against reachable default deployments of AIX 7.2/7.3 and VIOS 4.1. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a genuine high priority for organizations running IBM Power. … 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 | Apply the IBM-provided fix (interim fix/iFix or APAR) referenced in the IBM Security Bulletin 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 fixed build number, so pull the precise iFix/technology-level from that advisory (Patch available per vendor advisory - released patched version not independently confirmed from the provided data, so do not act on an invented version string). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a complete inventory of systems running IBM AIX 7.2, AIX 7.3, or PowerVM VIOS 4.1 to quantify exposure and identify mission-critical assets. …
