CVE-2024-20128
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 is a possible out of bounds read due to a missing bounds check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS09289881; Issue ID: MSV-2024.
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 missing bounds check in the Android Telephony component allows an out of bounds read, leading to remote denial of service without requiring any user interaction or elevated 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.
-
Check the Android versionRun 'adb shell getprop ro.build.version.release' or go to Settings > About Phone > Android versionAffected if The version listed is 13.0, 14.0, or 15.0 exactly
-
Confirm telephony component is presentCheck if the device has telephony capability by running 'adb shell pm list features | grep telephony' or verify the device is a phone rather than a tablet without cellular supportAffected if Telephony feature is present and enabled on the device
-
Identify the telephony service statusRun 'adb shell dumpsys package com.android.phone' to check if the Phone application is installed and enabledAffected if The com.android.phone package is installed and running
The device is affected if it runs Android 13.0, 14.0, or 15.0 and has the Android Telephony component enabled, which is the default state on most Android phones.

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 · scopedApply the vendor patch (ALPS09289881) to the affected Android Telephony component to add proper bounds validation before memory access.
Upgrade to Android version that includes MediaTek patch ALPS09289881 (contact device vendor for specific build numbers)
- Check for system updates on your Android device and apply any available updates that include MediaTek security patches
- If your device is from a manufacturer using MediaTek chipsets, check the manufacturer's security advisory for the MSV-2024 patch (ALPS09289881)
- Contact your device manufacturer or carrier for specific firmware versions containing the fix if automatic updates are not available
- For enterprise environments, consider network-level mitigations to block malicious telephony packets as a temporary measure until the update is applied
