CVE-2022-32640
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 meta wifi, 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: ALPS07441652; Issue ID: ALPS07441652.
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 confidenceIn meta wifi, there is an out-of-bounds write vulnerability due to a missing bounds check. This allows local privilege escalation to System execution level 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.
-
Check Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Version is exactly 11.0 or 12.0
-
Verify meta wifi component presenceCheck for the meta wifi service or binary on the device. This may be located in /system/bin/ or /vendor/bin/ as 'metawifi' or similar. List contents with 'ls -la /system/bin/ | grep -i wifi' and 'ls -la /vendor/bin/ | grep -i meta' via ADBAffected if A meta wifi binary or service exists on the device
-
Confirm device uses affected MediaTek chipsetRun 'getprop ro.hardware' or 'getprop ro.mediatek.platform' via ADB to identify if the device uses a MediaTek chipset, since the patch ALPS07441652 indicates MediaTek involvementAffected if Device uses a MediaTek chipset and runs Android 11.0 or 12.0 with meta wifi present
A device is affected if it runs Android 11.0 or 12.0 and contains the vulnerable meta wifi component from MediaTek, allowing local privilege escalation without user interaction.
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 ALPS07441652 to the affected meta wifi component. As this enables local privilege escalation to System level with no user interaction required, priority should be high despite the medium CVSS score.
Android 13 (which includes the backported security patches) or await OEM-specific security update containing MediaTek patch ALPS07441652
- 1. Check the current Android security patch level on the device: Go to Settings > About Phone > Security Patch Level
- 2. Apply the latest Android security updates: Go to Settings > System > System Update > Check for Updates
- 3. If no update is available, contact the device manufacturer (OEM) to request the patch for MediaTek vulnerability CVE-2022-32640 (Patch ID: ALPS07441652)
- 4. Verify the security patch level includes the fix - the fix should be included in Android security bulletins from late 2022 (approximately October 2022 or later)
