CVE-2022-20512
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 navigateUpTo of Task.java, there is a possible way to launch an intent handler with a mismatched intent due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-238602879
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 · high confidenceA vulnerability in Android's Task.java navigateUpTo function allows local privilege escalation due to improper input validation. The flaw permits launching an intent handler with a mismatched intent, enabling an attacker to elevate privileges locally without user interaction or additional 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.
-
Verify Android versionCheck the device or system settings for the Android version, or use 'getprop ro.build.version.release' via ADB shell. Alternatively, check Build.VERSION.RELEASE in application code.Affected if The installed Android version is exactly 13.0 (not 12.x, 14.x, or other variants)
-
Confirm framework component presenceVerify that the Android framework includes the Task.java class with the navigateUpTo function. This is typically part of the system framework (framework.jar or similar) on the device.Affected if The device runs Android 13.0 and includes the vulnerable navigateUpTo function in the Task class
-
Check for intent-related security eventsReview system logs (logcat) or security audit logs for any unusual or unauthorized intent navigation operations using navigateUpTo, particularly those with mismatched intent parameters.Affected if Logs show unexpected calls to navigateUpTo with manipulated intent data that may indicate exploitation attempts
A device is affected if it runs exactly Android version 13.0 and contains the vulnerable navigateUpTo function in the Task.java 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 dataApply the vendor patch for CVE-2022-20512 through Android system updates. Organizations should ensure devices receive the latest Android-13 security patches from device manufacturers.
