IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to obtain sensitive information or cause a denial of service due to an integer overflow.
AnalysisAI
Integer overflow in IBM AIX 7.2, 7.3, and PowerVM VIOS 4.1 allows a local attacker with limited privileges to extract sensitive information or trigger a denial of service under specific high-complexity conditions. Rooted in CWE-190 (Integer Overflow or Wraparound), the vulnerability carries a CVSS 3.1 base score of 3.6 (Low), reflecting the mandatory local access requirement and elevated attack complexity. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local, authenticated session on the affected system with at least a standard (non-root) user account, as indicated by CVSS PR:L and AV:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 3.6 (Low) accurately reflects the constrained threat profile: AV:L requires the attacker to already have local system access, AC:H indicates non-trivial exploitation conditions that are not reliably reproducible across all configurations, and PR:L mandates at least a standard user 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 | Consult the IBM Security Advisory at https://www.ibm.com/support/pages/node/7283858 for the specific APARs or Technology Level updates that address this vulnerability on AIX 7.2, AIX 7.3, and VIOS 4.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
