CVE-2026-4870 Jun 12, 20:52 HIGH PATCH This Week

Denial of service in IBM Qiskit SDK versions 0.43.0 through 2.5.0 allows remote attackers to crash the parser via uncontrolled recursion, triggering a segmentation fault. The CVSS 7.5 score (AV:N/AC:L/PR:N/UI:N) reflects unauthenticated network-reachable exploitation with high availability impact, though no public exploit identified at time of analysis. Affects quantum-computing workloads that ingest untrusted Qiskit/OpenQASM input.

CVE-2026-19795 Sep 03, 19:56 MEDIUM PATCH This Month

IBM Qiskit SDK versions 2.1.0 through 2.5.1 crash when deserializing a specially crafted QPY (Quantum Python) payload, due to a CWE-502 deserialization flaw that triggers a segmentation fault. Local attackers who can supply malicious QPY data to a deserializing process can cause the application to crash, resulting in denial of service with no confidentiality or integrity impact. No public exploit code or active exploitation has been identified at time of analysis, and IBM has released a patch via its support portal.
