CVE-2026-0069
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 verifySignature of ApkChecksums.java, there is a possible way to cause a crash due to resource exhaustion. This could lead to local denial of service 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 resource exhaustion vulnerability exists in the verifySignature function of ApkChecksums.java within the Android platform. An attacker can exploit this by providing a specially crafted APK that triggers excessive resource consumption during signature verification, causing the system to crash and resulting in local denial of service.

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 OS versionOn the Android device, go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if The device is running Android 14.0 exactly (not 14.0.1, 14.0.2, or later versions)
-
Identify APK installation or verification activityMonitor or log APK installation operations on the device. This includes app installations via Play Store, side-loaded APKs, or any operation that triggers verifySignature in ApkChecksums.javaAffected if APK signature verification is performed on the device (this is default behavior during app installation)
-
Verify the vulnerable code path existsInspect the framework JAR or source for android/content/res/ApkChecksums.java. Check if the verifySignature method lacks resource limit validation (e.g., no timeout, no memory bounds checking, no iteration limits)Affected if The verifySignature method in ApkChecksums.java does not implement proper resource limits for APK signature verification operations
A device is affected if it runs Android 14.0 exactly and processes APK signature verification, since the lack of resource limits in verifySignature allows resource exhaustion leading to denial of service.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedImplement resource limits and bounds checking in the verifySignature function to prevent exhaustion. Consider adding timeouts, memory limits, or input validation on the APK data being verified.
Android 14.1 or later / Latest available Android security patch
- Check the current Android version on the affected device (Settings > About Phone > Android version)
- Verify the device is running Android 14.0 (the affected version)
- Apply any available system updates through Settings > System > Software Update
- Alternatively, check with the device manufacturer for the latest security patch that addresses this vulnerability
- After updating, verify the Android version has changed from 14.0 to confirm the update was applied
