CVE-2026-0088
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 getCallingAppLabel of CertInstaller.java, there is a possible way to hide a sensitive security dialogue due to misleading or insufficient UI. 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 · moderate confidenceA vulnerability in the getCallingAppLabel method of Android's CertInstaller allows a malicious application to manipulate or obscure the identity of the calling application when displaying security-sensitive certificate installation dialogues. This UI misrepresentation can trick users or the system into trusting a malicious app, leading to local privilege escalation through unauthorized certificate installation.

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 and note the exact version numberAffected if Version is 14.0, 15.0, or 16.0 exactly
-
Verify CertInstaller package presenceCheck if the com.android.certinstaller package exists on the device using package manager: pm list packages certinstaller or via Settings > Apps > Show system apps looking for CertInstallerAffected if CertInstaller package is installed and accessible
-
Confirm security patch levelGo to Settings > About Phone > Security patch level and note the date. Compare against the vendor patch date for CVE-2026-0088 (if known) or verify patch is applied through system update checkAffected if Security patch level predates the CVE fix or remains unpatched
-
Check certificate installation behaviorAttempt a test certificate installation (Settings > Security > Install from storage) and observe if the calling app label displays correctly in the certificate trust prompt dialogAffected if The calling app label shown is missing, generic, or does not match the actual requesting application
A device is affected if running Android 14.0, 15.0, or 16.0 with CertInstaller present and without the CVE-2026-0088 security patch applied to the CertInstaller 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 Android system patch for CVE-2026-0088 when released. Until then, users should be advised to only install certificates from trusted sources and avoid side-loading apps from unknown developers.
