CVE-2024-20125
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 vdec, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained System privileges. User interaction is not needed for exploitation. Patch ID: ALPS09046782; Issue ID: MSV-1728.
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 confidenceAn out-of-bounds write vulnerability exists in the video decoder (vdec) component due to a missing bounds check, allowing a local attacker with System privileges to escalate privileges. The vulnerability does not require user interaction.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Confirm Android version is 13.0 or 14.0Open Settings > About Phone to view the Android version, or run 'adb shell getprop ro.build.version.release'Affected if The Android version listed is 13.0 or 14.0 exactly
-
Identify if video decoder (vdec) component is presentRun 'adb shell ls -la /vendor/lib/hw/vdec.*' or check for vdec-related libraries in /vendor/lib/ or /system/lib/Affected if A vdec component library exists in the system partition
-
Verify current process has System privilegesRun 'adb shell id' or check the UID of the process attempting to exploit (process must run as System/uid 1000 or higher)Affected if The exploiting process runs with System-level privileges (UID 1000) rather than an unprivileged user
You are affected if your device runs Android 13.0 or 14.0 and contains the vulnerable vdec component accessible to a System-privileged attacker.

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 ALPS09046782 to address the missing bounds check in the vdec component.
Latest Android security patch level (contact OEM for specific version containing ALPS09046782)
- Check with your device OEM (Original Equipment Manufacturer) for the latest Android security patch level that includes MediaTek patch ALPS09046782
- Verify the device has received the security update containing the MSV-1728 fix
- If the OEM has not released an update containing this patch, contact the device vendor or MediaTek directly for patch status
- For enterprise-managed devices, ensure Mobile Device Management (MDM) policies restrict System-level access to trusted applications only as an additional hardening measure
