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 · unedited
An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), Q(10.0), and R(11.0) software. Attackers can bypass Factory Reset Protection (FRP) via StatusBar. The Samsung ID is SVE-2020-17888 (December 2020).

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 confidence

A Factory Reset Protection (FRP) bypass vulnerability in Samsung mobile devices running Android O(8.x) through R(11.0). Attackers can circumvent the FRP security mechanism (which requires Google account credentials after factory reset) by exploiting the StatusBar component, allowing unauthorized device access and bypassing the intended anti-theft protection.

MitigationSamsung addressed this vulnerability in their December 2020 security update. Users should ensure their devices receive the latest Samsung security patch. Organizations should inventory affected devices and enforce patch management policies.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Samsung mobile devices in the environment
    Review device inventory or physically check Settings > About Phone > Model number to confirm the device manufacturer is Samsung
    Affected if The device is a Samsung mobile device running Android 8.0-11.0 and the December 2020 security update has not been applied
  2. Check the Android version installed
    On the device, go to Settings > About Phone > Android version. Verify the version is 8.0, 8.1, 9.0, 10.0, or 11.0
    Affected if Android version matches 8.0, 8.1, 9.0, 10.0, or 11.0
  3. Check the security patch level
    On the device, go to Settings > About Phone > Security patch level. Compare the date shown against December 2020
    Affected if Security patch level is dated before December 2020 (e.g., November 2020 or earlier)

A Samsung mobile device is affected if it runs Android 8.0 through 11.0 and has not received the December 2020 security update, as the vulnerability allows bypassing the Factory Reset Protection feature through the StatusBar component.
