AI Analysis
Technical Summary
CVE-2026-4870 describes a denial of service vulnerability in IBM Qiskit SDK versions 0.43.0 through 2.5.0. The vulnerability arises from uncontrolled recursion in the parser, which can be triggered by an attacker to cause a segmentation fault. This leads to a crash of the affected software, denying service to legitimate users. The vulnerability has a CVSS v3.1 base score of 7.5, indicating high severity, with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability.
Potential Impact
Successful exploitation results in a denial of service condition by crashing the IBM Qiskit SDK process through a segmentation fault. There is no impact on confidentiality or integrity of data. The availability of the affected software is disrupted until recovery or restart.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Users should monitor IBM's official channels for updates and apply patches once available.
