AI Analysis
Technical Summary
CVE-2026-17004 is a vulnerability in IBM i versions 7.3 through 7.6 where a remote attacker can cause the system to enter an infinite loop, leading to denial of service. The issue stems from a loop construct with an unreachable exit condition (CWE-835). The vulnerability requires no privileges and no user interaction, and it can be exploited remotely over the network. The CVSS v3.1 base score is 7.5, reflecting high severity due to the impact on availability.
Potential Impact
The primary impact is a denial of service condition caused by an infinite loop, which can make the affected IBM i system unresponsive or degrade its availability. There is no impact on confidentiality or integrity according to the CVSS vector.
