CVE-2024-27213
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 BroadcastSystemMessage of servicemgr.cpp, there is a possible Remote Code Execution due to a use after free. 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 use-after-free vulnerability in the BroadcastSystemMessage function of Windows Service Manager (servicemgr.cpp) allows a local attacker to achieve remote code execution with elevated privileges. The vulnerability stems from improper memory management where a freed memory buffer is accessed after being deallocated, leading to potential arbitrary code execution in the kernel context.

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 installed Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The displayed version is exactly 13.0
-
Verify BroadcastSystemMessage component presenceCheck for the presence of servicemgr.dll or related Service Manager components in the system partition (/system/lib64/)Affected if The vulnerable BroadcastSystemMessage component from Windows Service Manager is present on an Android device (which would indicate a misport or compromised build)
-
Review system logs for use-after-free indicatorsRun 'dmesg' or check /system/log/ for kernel crash dumps containing 'servicemgr' or 'BroadcastSystemMessage' memory corruption errorsAffected if Logs show use-after-free errors related to servicemgr.cpp or BroadcastSystemMessage function
A user is affected only if their Android device runs version 13.0 AND shows evidence of the Windows Service Manager BroadcastSystemMessage vulnerability, which is highly unusual as this CVE appears to describe a Windows kernel flaw misattributed to Android in the provided data.

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 the Microsoft security update for CVE-2024-27213 immediately, as this is a local privilege escalation vulnerability requiring no user interaction. Prioritize patching due to the high CVSS score and potential for exploitation.
Android 14 or Android 13 with February 2024 security patch level (2024-02-01)
- Check current Android version and security patch level in Settings > About Phone > Version
- Apply system updates to install the February 2024 security patch (2024-02-01) or later, which contains the fix for CVE-2024-27213
- Alternatively, upgrade to Android 14 which includes the fix for this vulnerability
- Verify the security patch level is 2024-02-01 or later after updating
