CVE-2024-32906
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 AcvpOnMessage of avcp.cpp, there is a possible EOP due to uninitialized data. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 local privilege escalation vulnerability exists in AcvpOnMessage function in avcp.cpp due to uninitialized data. The uninitialized data can be leveraged to gain elevated (root/system) privileges locally without requiring any user interaction or additional execution privileges.

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 if avcp service exists on the deviceRun 'ps -A | grep -i avcp' or check /system/bin/ for avcp binary to see if the Android Vendor Certification Program component is presentAffected if The avcp binary or service is found and the device security patch level is before the CVE fix date
-
Verify Android security patch levelCheck Settings > About Phone > Security Patch Level or run 'getprop ro.build.version.security_patch'Affected if Security patch level is earlier than the date when Google released the fix for this CVE (typically the June 2024 or subsequent Android security bulletin)
-
Identify avcp.cpp component versionLocate the avcp binary in /system/bin/ or /vendor/bin/ and check its file properties, or search for 'AcvpOnMessage' in any avcp-related files on the deviceAffected if The avcp component is present and contains the AcvpOnMessage function without the CVE fix applied
-
Check for root privileges already obtainedRun 'id' command to check current user privileges; check for unexpected root shells or unauthorized root accessAffected if Any unauthorized root-level access is detected, as this could indicate active exploitation of this or similar vulnerabilities
The device is affected if the avcp component is present and the Android security patch level predates the CVE fix, as the uninitialized data flaw in AcvpOnMessage allows local privilege escalation to root/system without user interaction.

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 which should properly initialize data structures in the AcvpOnMessage function. If no patch available, code review of avcp.cpp to identify and initialize all data structures before use.
