CVE-2026-16824: CWE-400 Uncontrolled Resource Consumption in IBM AIX
CVE-2026-16824 is a high-severity vulnerability in IBM AIX versions 7.2 and 7.3, as well as IBM PowerVM VIOS 4.1, that allows a remote attacker to cause a denial of service through unbounded recursion. This uncontrolled resource consumption can lead to system instability or crash. No official patch or remediation details are currently available.
AI Analysis
Technical Summary
This vulnerability, identified as CWE-400 (Uncontrolled Resource Consumption), affects IBM AIX 7.2, 7.3, and IBM PowerVM VIOS 4.1. It allows a remote attacker to trigger unbounded recursion, resulting in denial of service. The CVSS v3.1 base score is 7.5, indicating high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability (denial of service). There is no vendor advisory or patch information provided at this time.
Potential Impact
An attacker can remotely cause a denial of service condition by exploiting unbounded recursion, which consumes system resources excessively and may crash or destabilize the affected systems. There is no reported impact on confidentiality or integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting network access to affected systems and monitoring for unusual resource consumption patterns related to this vulnerability.
