CVE-2020-0265
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 Telephony, there are possible leaks of sensitive data due to missing permission checks. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-150155839
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 confidenceThis is a local information disclosure vulnerability in the Android Telephony component where missing permission checks allow sensitive data to be leaked without requiring any additional execution privileges or user interaction. The vulnerability affects Android-11 and could expose telephony-related sensitive information to unprivileged local applications or processes.

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.
-
Check the Android version on the deviceGo to Settings > About Phone and verify the Android version is exactly 11.0Affected if The Android version shows 11.0 - only this specific version is affected, later versions like 11.0.1, 11.0.2, etc. are not in the affected range
-
Verify the security patch levelGo to Settings > About Phone > Security patch level and check the dateAffected if The device is running Android 11.0 with a security patch level prior to the fix release - the specific patch date varies by device and carrier but was addressed in subsequent monthly Android security updates
-
Confirm Telephony functionality is presentCheck if the Phone or Telephony application is installed and functional on the deviceAffected if Telephony features are available and accessible on the device - the vulnerability affects any device where the Telephony component is present and operational
A device is affected if it runs Android version 11.0 exactly and has not received the security update that implements proper permission checks in the Telephony component.

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 dataThe fix requires implementing proper permission checks in the affected Telephony code paths to ensure only authorized components can access sensitive telephony data. This is a source-code-level fix that would be delivered through Android's regular security patch process.
