CVE-2022-32620
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 mpu, there is a possible memory corruption due to a logic error. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07541753; Issue ID: ALPS07541753.
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 confidenceA logic error in the MPU (Memory Protection Unit) causes memory corruption, allowing local privilege escalation from System-level execution privileges. No user interaction is required for exploitation. The vulnerability stems from incorrect logic in the memory protection handling code.

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 OS versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Version is 10.0, 11.0, 12.0, or 13.0 exactly
-
Check security patch levelGo to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shellAffected if Security patch level is earlier than the vendor-specific patch date for ALPS07541753
-
Check build fingerprint for patch presenceRun 'getprop ro.build.fingerprint' via ADB shell to compare against vendor firmware images containing the fixAffected if Build fingerprint does not contain the fixed MPU logic from patch ALPS07541753
The device is affected if running Android 10.0, 11.0, 12.0, or 13.0 and the vendor patch ALPS07541753 has not been applied, as evidenced by security patch level or build fingerprint.
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 ALPS07541753 which corrects the logic error in the MPU implementation. Since this is a kernel-level memory protection vulnerability, ensure the patch is integrated into the device firmware and verify proper memory protection behavior post-patch.
Android Security Patch Level containing fix for ALPS07541753 (typically included in monthly Android security updates from June 2022 onwards or per vendor release schedule)
- Check your device manufacturer's Android security patch level in Settings > About Phone > Software Information > Security Patch Level
- Verify the Security Patch Level is later than the date containing the fix for ALPS07541753
- If an update is available, go to Settings > System > Software Update and install the latest update
- After updating, verify the Security Patch Level has been updated to confirm the fix is applied
- Alternatively, contact your device manufacturer or MediaTek for specific firmware updates containing patch ALPS07541753
