CVE-2025-59504
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 · uneditedHeap-based buffer overflow in Azure Monitor Agent allows an unauthorized attacker to execute code locally.
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 confidenceHeap-based buffer overflow vulnerability in Azure Monitor Agent enables an unauthenticated local attacker to achieve code execution through memory corruption. The vulnerability stems from improper bounds checking when handling data in heap-allocated buffers.

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 Azure Monitor Agent installationOn Windows: Check registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AzureMonitorAgent or look for 'Azure Monitor Agent' in Programs and Features. On Linux: Run 'dpkg -l | grep azure-monitor-agent' or 'rpm -qa | grep azure-monitor-agent'.Affected if Azure Monitor Agent is not found on the system, meaning the system is not affected.
-
Determine installed versionOn Windows: Run 'Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AzureMonitorAgent | Select-Object DisplayVersion' or right-click the agent executable in Program Files\Azure Monitor Agent and view Properties > Details. On Linux: Run 'azure-monitor-agent --version' or check the package details.Affected if The installed version is less than 1.37.1.
-
Confirm agent is runningOn Windows: Run 'Get-Service | Where-Object {$_.DisplayName -like "*Azure Monitor*"}' or check Task Manager for AzureMonitorAgent.exe. On Linux: Run 'ps aux | grep azuremonitoragent'.Affected if The vulnerable version is running on the system.
If Azure Monitor Agent is installed and the running version is earlier than 1.37.1, the environment is affected by this heap-based buffer overflow vulnerability.

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 · scoped1.37.1
Apply vendor-supplied patches for Azure Monitor Agent when available. Prioritize deployment on systems with the lowest user privilege level and implement application whitelisting to limit potential impact until patch is applied.
Azure Monitor Agent 1.37.1 or later
- Check the currently installed Azure Monitor Agent version on the system
- Download Azure Monitor Agent version 1.37.1 or later from the official Microsoft Download Center or Azure portal
- Install the updated Azure Monitor Agent MSI package, or update via Azure Portal if the agent is deployed as a VM extension
- Restart the Azure Monitor Agent service if required
- Verify the installed version is 1.37.1 or higher to confirm the vulnerability is addressed
