CVE-2018-9139
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOn Samsung mobile devices with N(7.x) software, a buffer overflow in the vision service allows code execution in a privileged process via a large frame size, aka SVE-2017-11165.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA buffer overflow vulnerability exists in the vision service on Samsung mobile devices running N(7.x) software. The flaw is triggered by a large frame size, which allows an attacker to achieve code execution in a privileged system process.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device is Samsung mobileCheck device model and manufacturer in Settings > About PhoneAffected if Device is not a Samsung mobile device (this CVE only affects Samsung devices)
-
Check Android version is N (7.x)Go to Settings > About Phone > Android version; verify the version is 7.0, 7.1, 7.1.1, or 7.1.2Affected if Android version is 7.0, 7.1, 7.1.1, or 7.1.2 and the device is Samsung Mobile
-
Verify vision service is presentCheck for vision-related apps or services in Settings > Apps, or check running processes for vision service daemonAffected if Vision service is present and running on the device
-
Review for indicators of compromiseMonitor for unexpected vision service behavior, unusual network connections from vision-related processes, or evidence of exploitation attempts in device logsAffected if Vision service exhibits unexpected behavior or shows signs of exploitation
A Samsung mobile device running Android N versions 7.0-7.1.2 with the vision service enabled is potentially affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply Samsung security patches for SVE-2017-11165; if unavailable, disable or restrict the vision service and monitor for indicators of compromise.
Android O (8.x) or later if supported by device; otherwise latest available Samsung security patch for the device
- 1. Identify the exact Samsung device model number (found in Settings > About phone > Model number)
- 2. Check Samsung's security update portal at security.samsungmobile.com for the SVE-2017-11165 patch availability
- 3. Navigate to Settings > Software update > Download and install on the device
- 4. Ensure the device is connected to Wi-Fi and charged during the update process
- 5. Verify the installed Android Security Patch Level: go to Settings > About phone > Software information > Security patch level
- 6. Confirm the device has the May 2018 or later security patch (which includes fixes for SVE-2017-11165)
