CVE-2026-16929: CWE-787 Out-of-bounds Write
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to a buffer overflow.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-16929) affects IBM i versions 7.3 through 7.6 and is classified as a CWE-787 out-of-bounds write due to a buffer overflow condition. A remote attacker with authentication privileges could exploit this flaw to obtain sensitive information. The CVSS 3.1 base score is 5.3 (medium), with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability (denial of service) rather than confidentiality or integrity. No known exploits are reported in the wild, and no vendor remediation level or patch information is currently available.
Potential Impact
The impact is limited to potential denial of service or sensitive information disclosure caused by a buffer overflow. The vulnerability requires remote authentication but no user interaction. There is no indication of integrity or confidentiality impact beyond sensitive information disclosure. No active exploitation is known.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, monitor IBM's advisories for updates. Until a patch is available, restrict remote authenticated access to trusted users only and apply standard access controls.
