The flaw does not enable code execution or privileged escalation, but it does expose potentially sensitive information such as personal messages, application data, or authentication details that are normally concealed from other apps. This leads to an information\u2011disclosure risk for the confidentiality of the device\u2019s user data, corresponding to an access control weakness.", "risk_and_exploitability": "The CVSS score of 4.7 indicates moderate severity, reflecting that the flaw requires physical possession of the device and the ability to launch Samsung DeX. The EPSS score of less than 1\u00a0% suggests that exploitation attempts are unlikely. The vulnerability is not listed in the CISA KEV catalog, indicating no known public exploits. Attackers would need to be physically present and able to activate Samsung DeX in order to read hidden notification contents; no remote trigger or software exploit is indicated by the current data."}}}}, "created": "2026-04-13T12:37:13.332766+00:00", "title": "Access Control Flaw in Samsung DeX Allows Physical Disclosure of Hidden Notifications", "updated": "2026-04-15T15:45:07.536638+00:00", "vendors": ["samsung", "samsung$PRODUCT$mobile_devices", "samsung_mobile", "samsung_mobile$PRODUCT$samsung_mobile_devices"]}
