CVE-2026-12109: CWE-787 Out-of-bounds Write in IBM Security Verify Access
Description
CVE-2026-12109 is an out-of-bounds write vulnerability in IBM Security Verify Access and IBM Verify Identity Access. It affects versions 10.0 through 10.0.9.2 and 11.0 through 11.0.3. An attacker with administrative privileges and local management interface access could exploit this flaw to execute arbitrary code due to an unbounded write to a fixed-size stack buffer. The vulnerability has a medium severity with a CVSS score of 5.5.

Technical Analysis
This vulnerability (CVE-2026-12109) involves an out-of-bounds write (CWE-787) in IBM Security Verify Access versions 10.0 to 10.0.9.2 and IBM Verify Identity Access versions 11.0 to 11.0.3. The flaw allows an attacker who already has administrative privileges and local management interface access to perform an unbounded write to a fixed-size stack buffer, potentially leading to arbitrary code execution. The CVSS 3.1 base score is 5.5, reflecting medium severity with network attack vector, high attack complexity, and required privileges.
Potential Impact
An attacker with administrative privileges and local management interface access could exploit this vulnerability to execute arbitrary code on the affected system. This could lead to system compromise or disruption of service. The impact includes limited confidentiality and integrity loss but high availability impact.
Mitigation Recommendations
No explicit patch or 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, restrict administrative and local management interface access to trusted personnel only.
