Security readout for executives and security teams
Plain-English summary
This CVE describes a privacy flaw in Samsung mobile devices running N(7.x) or O(8.x) software where clipboard contents could be visible while the phone is locked through the emergency contact picker. Business risk depends on whether sensitive data was copied to the clipboard and whether legacy Samsung devices remain in use.
Executive priority
Treat this as a legacy mobile privacy exposure. Prioritize it if the organization still permits old Samsung phones, especially in roles handling credentials, customer data, or regulated information.
Technical view
Samsung tracked this as SVE-2018-11806 in the September 2018 bulletin. The public description identifies locked-state clipboard content visibility through the emergency contact picker on Samsung N(7.x) and O(8.x) software. The source bundle provides no CVSS score, CWE, model list, or detailed fix text.
Likely exposure
Exposure is most likely limited to older Samsung mobile devices running Android N(7.x) or O(8.x). The sources do not identify specific models, builds, or enterprise configurations.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. The described scenario implies local access to a locked device and clipboard data being present.
Researcher notes
Public evidence is sparse. The record names Samsung N/O software, locked-state clipboard visibility, emergency contact picker, and Samsung ID SVE-2018-11806. It does not provide CVSS, affected model granularity, exploit status, or remediation mechanics.
Mitigation direction
- Check Samsung guidance for SVE-2018-11806 from September 2018.
- Update affected Samsung devices to a vendor-supported patched release.
- Retire or isolate legacy Samsung N/O devices where updates are unavailable.
- Use MDM policy to identify outdated Android and Samsung patch levels.
Validation and detection
- Inventory Samsung devices still running Android N(7.x) or O(8.x).
- Verify each device's Samsung security patch level against vendor guidance.
- Confirm whether affected devices are still allowed on corporate networks.
- Review mobile handling policies for copied secrets and sensitive clipboard use.
