CVE-2022-32634
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 ccci, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07138646; Issue ID: ALPS07138646.
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 MediaTek's ccci (common channel communication interface), an out of bounds write vulnerability exists due to improper input validation. This allows a local attacker with System execution privileges to escalate privileges further. The vulnerability requires no user interaction and is exploitable locally.

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 11.0, 12.0, or 13.0 specifically
-
Verify MediaTek chipsetCheck device specifications for MediaTek processor or run 'getprop ro.hardware' or 'cat /proc/cpuinfo' via ADBAffected if Device uses a MediaTek chipset (ccci is MediaTek-specific)
-
Confirm ccci component presenceRun 'ls -la /vendor/bin/ccci' or check for ccci-related processes/services via 'ps -A | grep -i ccci' via ADBAffected if The ccci component exists and is running on the device
-
Check baseband version if accessibleRun 'getprop gsm.version.baseband' or check modem version in Settings > About Phone > Baseband version via ADBAffected if Unable to verify patch ALPS07138646 has been applied (patched versions vary by carrier and region)
User is likely affected if running Android 11.0, 12.0, or 13.0 on a MediaTek-powered device with the ccci component present, and the vendor patch ALPS07138646 has not been applied.
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 ALPS07138646 which implements proper input validation to prevent the out of bounds write in the ccci component. Verify the patch does not introduce regressions in modem-application processor communication.
Android Security Patch Level >= November 2022 (or the nearest monthly security update containing this fix from your specific OEM)
- Check your current Android security patch level in Settings > About Phone > Security Patch Level
- Contact your device manufacturer (OEM) to verify they have released an Android security update that includes MediaTek patch ALPS07138646
- Apply the latest available Android security update from your device manufacturer
- If your OEM has provided a separate MediaTek firmware/modem update, apply that as well
- Verify the security patch level has been updated post-installation
