CVE-2026-16917: CWE-190 Integer Overflow or Wraparound in IBM AIX
CVE-2026-16917 is a critical integer overflow vulnerability affecting IBM AIX versions 7.2 and 7.3, as well as IBM PowerVM VIOS 4.1. This flaw could allow a remote attacker to execute arbitrary code on the affected systems without any user interaction or privileges. The vulnerability is due to improper handling of integer values leading to overflow or wraparound conditions.
AI Analysis
Technical Summary
This vulnerability involves an integer overflow or wraparound condition in IBM AIX 7.2, 7.3, and IBM PowerVM VIOS 4.1. The flaw could be exploited remotely by an unauthenticated attacker to execute arbitrary code, potentially compromising confidentiality, integrity, and availability of the affected systems. The CVSS v3.1 base score is 9.8, indicating a critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed.
Potential Impact
Successful exploitation allows remote code execution, granting an attacker full control over the affected system. This impacts confidentiality, integrity, and availability severely, enabling compromise of system operations and data.
Mitigation Recommendations
No patch or official remediation information is provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is available, consider restricting network exposure of affected systems and monitor for unusual activity related to this vulnerability.
