IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to cause a denial of service due to an integer overflow.
AnalysisAI
Integer overflow in IBM i versions 7.3 through 7.6 allows remote authenticated attackers to cause a denial of service condition. The vulnerability (CWE-190) is network-reachable but requires prior authentication, and its impact is limited to partial availability degradation with no confidentiality or integrity consequences. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires remote network access and a valid authenticated session on the IBM i system (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 Medium score accurately reflects the constrained real-world risk: the authentication requirement (PR:L) eliminates opportunistic unauthenticated internet attackers, and the partial availability impact (A:L) caps blast radius well below a full service outage. … 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 IBM vendor advisory at https://www.ibm.com/support/pages/node/7285937; administrators should consult the advisory for the specific PTF (Program Temporary Fix) or Technology Refresh level required for their IBM i release (7.3, 7.4, 7.5, or 7.6). … Detailed patch versions, workarounds, and compensating controls in full report. |
