CVE-2023-20604
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 ged, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07494067; Issue ID: ALPS07494067.
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 confidenceThis is an out-of-bounds write vulnerability in the ged component caused by a missing bounds check. An attacker with existing System execution privileges can exploit this to escalate privileges locally without any user interaction.

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.
-
Identify Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is 11.0, 12.0, or 13.0 exactly
-
Locate the ged componentCheck if /system/vendor/bin/ged or /vendor/bin/ged exists on the device via ADB: 'ls -la /system/vendor/bin/ged' or 'ls -la /vendor/bin/ged'Affected if The ged binary or library files exist in vendor or system partitions
-
Verify ged is accessibleCheck ged file permissions and SELinux context via ADB shell: 'ls -laZ /vendor/bin/ged' or check if the process can be invoked by system-level appsAffected if The ged component is present and executable by system-privileged processes
The environment is affected if running Android 11.0, 12.0, or 13.0 with the ged component present and accessible to system-level execution contexts.

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 ALPS07494067 or update to the patched version containing the bounds check fix.
Android Security Patch Level incorporating MediaTek ALPS07494067 fix (typically 2023 or later monthly security update)
- Check the current Android Security Patch Level on the device in Settings > About Phone > Security Patch Level
- Verify the device is running a MediaTek chipset (this vulnerability affects MediaTek-specific ged driver)
- Apply the latest available Android Security Update from the device manufacturer that includes the MediaTek security bulletin with Patch ID ALPS07494067
- For MediaTek-based devices, ensure the update includes the fix for CVE-2023-20604 in the ged driver component
- If the manufacturer has not released an update, contact the device vendor or MediaTek for patched firmware
