IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to execute arbitrary code due to an out-of-bounds write.
AnalysisAI
Out-of-bounds write in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 enables a local, high-privileged attacker to execute arbitrary code. The vulnerability is rooted in a memory corruption flaw (CWE-787) that can corrupt adjacent memory regions during a write operation. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the target IBM AIX 7.2/7.3 or PowerVM VIOS 4.1 system with high privileges (PR:H per the CVSS vector), meaning the attacker must already hold root-equivalent or administrator-level credentials. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.7 reflects the constrained exploitation conditions: AV:L limits the attack to a locally present adversary, and PR:H demands that the attacker already hold high system privileges - effectively administrator or root-equivalent access on AIX or VIOS. … 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 | Organizations should consult the IBM security advisory at https://www.ibm.com/support/pages/node/7283858 for the authoritative fix guidance, including any available interim fixes (IFs) or technology levels (TLs) addressing CVE-2026-16914. … Detailed patch versions, workarounds, and compensating controls in full report. |
