CVE-2024-20142
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 V5 DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09291406; Issue ID: MSV-2070.
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 V5 DA, a missing bounds check allows an out-of-bounds write, which can be exploited for local privilege escalation. The attacker requires physical device access and user interaction to trigger the vulnerability.

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 versionOpen Settings > About Phone > Android version, or run 'adb shell getprop ro.build.version.release'Affected if The reported version is exactly 12.0, 13.0, 14.0, or 15.0
-
Verify build fingerprintRun 'adb shell getprop ro.build.fingerprint' to confirm the exact Android buildAffected if The build shows Android 12.0, 13.0, 14.0, or 15.0 as the base version
-
Confirm V5 DA component presenceCheck for the V5 DA service or daemon: run 'adb shell ps -A | grep -i v5' or examine /system for v5-related binaries or servicesAffected if The V5 DA component is present and running on the device
-
Verify user interaction requirementReview device usage patterns - the flaw requires a local attacker with physical access and some form of user interaction to triggerAffected if The device is physically accessible to untrusted users and the V5 DA component is enabled
A device is affected if it runs Android version 12.0, 13.0, 14.0, or 15.0 and has the V5 DA component present, since the vulnerability exists in this specific component within those versions.

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 vendor patch ALPS09291406 to all affected V5 DA installations. Until patched, restrict physical access to vulnerable devices and monitor for suspicious local access.
Contact your device OEM for the specific security update containing MediaTek patch ALPS09291406 (ALPS09291406)
- Contact your Android device manufacturer (OEM) to verify if they have released a security update containing the MediaTek patch ALPS09291406 for your specific device model
- Check your device's Settings > System > Security update to see if a newer patch level is available
- If available, apply the latest security update through Settings > System > Software Update
- Verify the patch has been applied by checking Settings > System > About phone > Security patch level
