IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service and compromise integrity due to a buffer overflow.
AnalysisAI
Buffer overflow (CWE-787) in IBM i 7.3 through 7.6 enables remote unauthenticated attackers to trigger denial of service and partial integrity compromise over the network. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no authentication, no user interaction, and no special configuration, though the specific IBM i subsystem or network service containing the flaw is not identified in available data. …

Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no special configuration or privileges are required - the vulnerable component must be reachable over the network from the attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 (Medium) reflects a meaningful but bounded risk posture: network-accessible with no authentication or interaction requirement (AV:N/AC:L/PR:N/UI:N) but limited to partial integrity and availability impact (I:L/A:L) with no confidentiality breach (C:N). … 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 vendor-released patch via IBM's support advisory at https://www.ibm.com/support/pages/node/7285847, which should enumerate the specific PTF numbers for each affected IBM i release (7.3, 7.4, 7.5, 7.6). … Detailed patch versions, workarounds, and compensating controls in full report. |
