1DescriptionCVE.org
IBM Qiskit SDK 2.1.0 through 2.5.1 could allow a local attacker to cause a denial of service due to improper handling of a specially crafted object during deserialization. A malicious QPY payload can trigger a segmentation fault, causing the application to crash when deserializing untrusted input.
AnalysisAI
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. …

Vulnerability AssessmentAI
| Exploitation | The target application must deserialize a QPY payload sourced from an attacker-controlled or attacker-influenced input - such as a shared directory, a file upload endpoint, or an automated pipeline ingesting external quantum circuits. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.2 with AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H accurately reflects a moderate local denial-of-service risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch is available per IBM's vendor advisory at https://www.ibm.com/support/pages/node/7285932; consult that page for the exact patched release version, as it was not specified in available intelligence data. … Detailed patch versions, workarounds, and compensating controls in full report. |
