CVE-2025-38743
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 · uneditedDell iDRAC Service Module (iSM), versions prior to 6.0.3.0, contains a Buffer Access with Incorrect Length Value vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Code execution and Elevation of privileges.
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 confidenceThe Dell iDRAC Service Module versions prior to 6.0.3.0 contain a buffer access vulnerability where an incorrect length value is used when accessing a buffer. A low-privileged local attacker can exploit this to achieve code execution and elevate privileges to higher permission levels.

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.
-
Confirm iDRAC Service Module is installedLocate the Dell iDRAC Service Module installation on the system. On Windows, check Program Files for Dell folders. On Linux, check /opt or /usr for dell directories. Use system inventory tools if available.Affected if The software is not found on the system, the user is not affected by this specific vulnerability.
-
Identify the installed versionFind the version information for the Dell iDRAC Service Module. Common methods include: checking the application properties in Windows Add/Remove Programs, running 'rpm -qa | grep idrac' or 'dpkg -l | grep idrac' on Linux, or examining version info in the installation directory.Affected if Unable to determine the version, assume the installed version may be affected.
-
Compare version against the affected rangeCompare the identified version to 6.0.3.0. The vulnerability affects all versions prior to 6.0.3.0.Affected if The installed version is lower than 6.0.3.0, the system is within the affected version range.
-
Verify service accessibility for local exploitationConfirm the iDRAC Service Module service or executable is present and accessible to local users. Check service status and file permissions on the installation directory.Affected if The service is running and accessible to low-privileged local users, the exploitation preconditions for this vulnerability are present.
A system is affected if Dell iDRAC Service Module is installed with a version lower than 6.0.3.0 and the service is accessible to local users.

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 · scoped6.0.3.0
Upgrade Dell iDRAC Service Module to version 6.0.3.0 or later to remediate the buffer access vulnerability.
6.0.3.0
- Navigate to Dell support website (www.dell.com) and search for iDRAC Service Module
- Locate the Dell iDRAC Service Module version 6.0.3.0 or later for your specific Dell PowerEdge server model
- Download the Dell Update Package (DUP) or appropriate installer for your iSM version
- Execute the installer following Dell's standard iSM installation procedure, typically requiring administrator/root privileges
- Verify the installation completed successfully by checking the iSM version through iDRAC web interface or command line
- Restart any dependent services if prompted to ensure the new version is fully operational
