CVE-2020-0374
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 · uneditedIn NFC, there is a possible permission bypass due to an unsafe PendingIntent. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-156251602
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 confidenceIn Android 11's NFC component, an unsafe PendingIntent allows a permission bypass that enables local privilege escalation. A malicious app could potentially intercept or manipulate the PendingIntent to gain elevated access without user interaction, requiring only User execution privileges.

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 Android version is 11.0Go to Settings > About Phone > Android version (or run 'getprop ro.build.version.release' via ADB)Affected if Version is exactly 11.0 (the affected version per the CVE)
-
Verify NFC is enabled on the deviceGo to Settings > Network & Internet > NFC (or check 'getprop nfc.ice.enabled' via ADB)Affected if NFC is turned ON - the vulnerability exists in the NFC framework component when active
-
Check for NFC system serviceRun 'dumpsys nfc' via ADB to inspect the NFC service status and PendingIntent configurationsAffected if NFC service is running and shows active PendingIntent handlers - these are the vulnerable code paths
-
Identify apps using NFC PendingIntentsReview app manifests or audit installed apps for NFC-related intent filters (android.nfc.action.TECH_DISCOVERED, android.nfc.action.TAG_DISCOVERED)Affected if Any app is registered to handle NFC intents - the unsafe PendingIntent can be intercepted or manipulated
Device is affected if running Android 11.0 with NFC enabled and apps utilizing NFC PendingIntent functionality are present - the permission bypass vulnerability exists in the NFC framework's PendingIntent handling on this specific Android version

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.
From vendor dataApply the Android 11 security patch (September 2020 or later) to address the vulnerability in the NFC framework. Organizations should ensure devices receive regular system updates and monitor for available patches from device OEMs.
