CVE-2022-32623
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 mdp, there is a possible out of bounds write due to incorrect error handling. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07342114; Issue ID: ALPS07342114.
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 confidenceOut-of-bounds write vulnerability in MediaTek's MDP (Mobile Display Processor) component caused by incorrect error handling. Allows local privilege escalation from System execution privileges to higher privileges without 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.
-
Check Android versionGo to Settings > About Phone > Android version or run 'getprop ro.build.version.release' in ADB shellAffected if Version is exactly 12.0 (the affected version listed)
-
Identify chipset vendorCheck device specifications or run 'getprop ro.hardware' or 'getprop ro.chipset' in ADB shell to determine if MediaTek chipset is presentAffected if Device uses a MediaTek chipset (MDP is MediaTek's Mobile Display Processor)
-
Verify MDP component presenceCheck for MDP driver/modules in /vendor/lib or /system/lib related to mdp, or examine kernel modules with 'lsmod | grep mdp' if availableAffected if MDP component is present and loaded on the device
-
Check vendor patch levelRun 'getprop ro.build.version.security_patch' in ADB shell to check the security patch dateAffected if Patch level is earlier than the ALPS07342114 fix (no fix applied)
Device is affected if it runs Android 12.0 on a MediaTek chipset with unpatched MDP component that allows privilege escalation via the out-of-bounds write vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 ALPS07342114 which corrects the error handling logic in the MDP component to prevent the out-of-bounds write condition.
- Contact your Android device manufacturer to verify they have incorporated MediaTek patch ALPS07342114 for CVE-2022-32623
- Apply the latest Android security patch level update released by your device manufacturer that includes this MediaTek fix
- Verify the device is running Android Security Patch Level dated August 2022 or later (when this vulnerability was addressed)
