CVE-2024-20025
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 da, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08541686; Issue ID: ALPS08541686.
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 confidenceAn integer overflow vulnerability in the 'da' (device access) component allows an attacker with System-level privileges to trigger an out-of-bounds write, potentially leading to further local privilege escalation. The vulnerability does not require user interaction and stems from insufficient bounds checking on integer operations.

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.
-
Verify Android versionRetrieve the device Android version using 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if The reported version is exactly 12.0, 13.0, or 14.0
-
Confirm system is unpatchedCheck the Android security patch level via 'getprop ro.build.version.security_patch' - compare against the vendor patch date for ALPS08541686Affected if The security patch level is older than the vendor fix date or the device has not received the ALPS08541686 patch
-
Identify 'da' component presenceList running daemons or services on the device and look for a process or service related to 'device access' (commonly named 'daemon', 'da', or similar device access services) using 'ps -A' or 'dumpsys'Affected if A device access daemon/service is running and the Android version matches the affected versions listed
The device is vulnerable if it runs Android 12.0, 13.0, or 14.0 and has not received the vendor patch ALPS08541686.

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 ALPS08541686 to address the integer overflow in the affected daemon component. Since this is a local privilege escalation vector, prioritize patching devices with elevated attack surface exposure.
- 1. Identify if the device uses a MediaTek chipset (check device specifications or settings)
- 2. Contact the device manufacturer (OEM) to verify if security patch ALPS08541686 has been applied
- 3. Check for available system/security updates in device Settings > System > Security Update (or Settings > About Phone > Software Update)
- 4. Apply any available security updates that include the MediaTek patch ALPS08541686
- 5. Verify the patch has been applied by confirming the security patch level in Settings > System > Security Update shows a date after the fix release
