IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to improper validation of an allocation size.
AnalysisAI
Denial of service in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 is reachable by unauthenticated remote attackers through improper validation of an allocation size, crashing the affected system or service without any user interaction. The vulnerability carries a CVSS 7.5 High score driven entirely by a complete availability impact against a network-accessible, zero-prerequisite attack path. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions are required beyond network reachability to the affected IBM AIX or PowerVM VIOS system: the CVSS vector AV:N/AC:L/PR:N/UI:N confirms remote unauthenticated exploitation against default configurations of IBM AIX 7.2/7.3 and VIOS 4.1. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H confirms the worst-case accessibility profile: no authentication, no interaction, and reachable from the network with low complexity. … 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-issued fix documented at https://www.ibm.com/support/pages/node/7283858; the exact patched version or Technology Level should be confirmed there, as the source data does not include a specific fix release number and citing an unconfirmed version would be misleading. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify and inventory all IBM AIX 7.2, 7.3, and PowerVM VIOS 4.1 systems accessible from the network; assess criticality and business impact of each instance. …
