CVE-2026-0047
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 dumpBitmapsProto of ActivityManagerService.java, there is a possible way for an app to access private information due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 confidenceIn dumpBitmapsProto of ActivityManagerService.java, a missing permission check allows any locally installed app to access private information (likely bitmap dump data) without proper authorization, leading to local privilege escalation.

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 Android versionGo to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via ADBAffected if Android version is exactly 16.0 (the only affected version)
-
Identify if dumpBitmapsProto is accessibleCheck if ActivityManager.dumpBitmapsProto() can be invoked by a standard (non-system) app. This typically requires examining if the ActivityManagerService dump interface is protected by DUMP permission.Affected if Any installed app can invoke ActivityManagerService dump methods without holding the DUMP permission
-
Verify permission enforcement on dump functionsAttempt to trigger ActivityManager dump from a non-privileged app context or inspect the ActivityManagerService.java code for dumpBitmapsProto to confirm absence of enforceDumpPermission() or equivalent checkAffected if The dumpBitmapsProto function lacks proper permission validation
-
Confirm local app access capabilityTest or verify that any locally installed app (without system privileges) can access bitmap dump data through the ActivityManagerService interfaceAffected if Non-privileged apps can retrieve private bitmap data via dumpBitmapsProto without authorization
The environment is affected if Android version is exactly 16.0 and any locally installed app can access dumpBitmapsProto in ActivityManagerService without requiring the DUMP permission.
