CVE-2026-18101: CWE-269 Improper Privilege Management
CVE-2026-18101 is a high severity vulnerability in IBM i versions 7.3, 7.4, 7.5, and 7.6. It involves improper privilege management due to incorrect handling of thread authority swaps, which could allow a local attacker to gain elevated privileges without user interaction.
AI Analysis
Technical Summary
This vulnerability in IBM i operating system versions 7.3 through 7.6 arises from improper management of thread authority swaps. A local attacker with limited privileges could exploit this flaw to escalate their privileges, potentially gaining full control over the affected system. The CVSS 3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability. No official patch or remediation level has been published at this time, and there are no known exploits in the wild.
Potential Impact
Successful exploitation could result in a local attacker gaining elevated privileges, leading to complete compromise of confidentiality, integrity, and availability of the affected IBM i system. This could allow unauthorized access to sensitive data and system functions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users only and monitor for suspicious activity related to privilege escalation attempts.
