2DescriptionNVD
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 a memory leak.
AnalysisAI
IBM i versions 7.3 through 7.6 expose authenticated remote attackers to a denial-of-service condition via a memory leak (CWE-401). An attacker with low-privilege credentials can repeatedly trigger the vulnerable code path over the network, causing progressive memory exhaustion that degrades or halts system services. …

Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated session on the IBM i system with at least low-privilege credentials (PR:L per CVSS); unauthenticated attackers cannot exploit this directly. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS score of 4.3 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L accurately frames this as a limited-scope availability-only vulnerability. … 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 fix by following IBM Security Advisory https://www.ibm.com/support/pages/node/7285844, which provides PTF identifiers and cumulative fix levels for IBM i 7.3, 7.4, 7.5, and 7.6. … Detailed patch versions, workarounds, and compensating controls in full report. |
