CVE-2022-32626
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 display, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07326239; Issue ID: ALPS07326239.
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 confidenceA bounds check error in MediaTek's display driver allows an out-of-bounds write that can be exploited for local privilege escalation. The vulnerability resides in the display component and requires System-level privileges to exploit, with no user interaction needed.

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 version is 11.0 or 12.0Run 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if Version equals 11.0 or 12.0 exactly (not 11.0.x or 12.0.x variants)
-
Verify MediaTek chipset is presentRun 'getprop ro.hardware' or check '/proc/cpuinfo' for MediaTek/MTK identifierAffected if Hardware/processor is identified as MediaTek or MTK chipset
-
Confirm MediaTek display driver is loadedCheck '/proc/mediatek/leds' or run 'ls -la /vendor/lib/modules/' for MediaTek display driver modules (*.ko files containing 'disp' or 'ddp')Affected if MediaTek display driver module exists and is loaded on the system
-
Verify security patch levelRun 'getprop ro.build.version.security_patch' to check the applied security patch dateAffected if Security patch level is earlier than the vendor patch ALPS07326239 release date
Device is affected if running Android 11.0 or 12.0 on a MediaTek chipset with an unpatched display driver (security patch predates the fix).

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 the vendor-supplied patch (ALPS07326239) by updating device firmware to the version containing the fix. This is a MediaTek chipset vulnerability requiring an OEM firmware update.
OEM-specific security update containing ALPS07326239 (typically included in Android Security Bulletins from October 2022 or later)
- 1. Identify if the device uses a MediaTek chipset (check device specifications or chipset info)
- 2. Check the current Android security patch level in Settings > About Phone > Security Patch Level
- 3. Contact the device manufacturer (OEM) for the security update containing patch ALPS07326239
- 4. Apply the OEM security update when available - this typically comes through system updates from the device manufacturer
- 5. Verify the security patch level has been updated to include the fix for CVE-2022-32626
