CVE-2022-32614
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 audio, 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: ALPS07310571; Issue ID: ALPS07310571.
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 MediaTek audio subsystem causes memory corruption that can be exploited for local privilege escalation. The vulnerability requires System-level execution privileges to exploit but needs no user interaction. The patch ID ALPS07310571 addresses this specific flaw in the audio driver 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.
-
Verify Android version is 12.0Check the Android version in Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if The device is running Android version 12.0 exactly (not 12L or other versions)
-
Confirm MediaTek chipset is presentRun 'getprop ro.hardware' or 'cat /proc/cpuinfo' via ADB to identify the chipset manufacturerAffected if The device uses a MediaTek (MTK) chipset; the vulnerability is in MediaTek-specific audio driver code
-
Check MediaTek audio driver patch statusQuery the system build property for the patch level or audio driver version using 'getprop' commands specific to the MediaTek audio HAL; consult device OEM documentation for exact property namesAffected if The audio driver patch ALPS07310571 has not been applied to the MediaTek audio subsystem
-
Verify system-level access existsConfirm the device has been rooted or you have elevated privileges; the vulnerability requires system-level execution privileges to exploitAffected if You have system-level (root) access and the device meets the other affected conditions
A user is affected if they are running Android 12.0 on a MediaTek-based device where the audio driver patch ALPS07310571 has not been applied.

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.
From vendor dataApply the vendor patch (ALPS07310571) to affected MediaTek-based Android devices. Since this is a platform-specific vulnerability in the audio driver, organizations should coordinate with device OEMs and ensure firmware updates are deployed.
