Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Network-reachable unauthenticated crash with no complexity barrier; C:N/I:N because impact is strictly availability via memory corruption with no scope change.

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 an out-of-bounds write.
AnalysisAI
Remote denial-of-service in IBM AIX 7.2 and 7.3 and PowerVM VIOS 4.1 is caused by a CWE-787 out-of-bounds write reachable by unauthenticated network attackers with no complexity prerequisites. The CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) reflects straightforward remote triggering with high availability impact but no confidentiality or integrity consequence. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The CVSS vector AV:N/AC:L/PR:N/UI:N indicates no special configuration or authentication is required - any remote unauthenticated host that can reach the vulnerable network service on IBM AIX 7.2/7.3 or PowerVM VIOS 4.1 can attempt exploitation. … 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) places this firmly in the high-severity band for availability, with no authentication or interaction barriers - any host that can reach the network service can attempt to trigger the crash. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated remote attacker sends specially crafted network packets to an IBM AIX or PowerVM VIOS system with the vulnerable service exposed, triggering an out-of-bounds write that corrupts memory in the service or kernel context. The resulting memory corruption causes a process crash or system panic, denying availability to users of the AIX system or, in the VIOS case, disrupting I/O services for all virtual machine logical partitions dependent on that VIOS instance. … |
| Remediation | Apply the IBM-released fix documented at https://www.ibm.com/support/pages/node/7283858, which provides APAR numbers and interim fix packages for AIX 7.2, AIX 7.3, and PowerVM VIOS 4.1; exact patched build levels are not included in this analysis dataset and must be obtained from the advisory directly. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all IBM AIX 7.2, 7.3, and PowerVM VIOS 4.1 systems via asset inventory and scanning tools, confirm patch availability from the vendor advisory, and notify infrastructure and operations teams of required urgent remediation. …
