CVE-2024-23908
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 · uneditedInsecure inherited permissions in some Flexlm License Daemons for Intel(R) FPGA software before version v11.19.5.0 may allow an authenticated user to potentially enable escalation of privilege via local access.
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 confidenceInsecure inherited permissions in FlexLM license daemons for Intel FPGA software allows authenticated local users to escalate privileges. The vulnerability stems from overly permissive file or service permissions that inherit to child processes, enabling a local authenticated attacker to manipulate the license daemon to gain elevated access.

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.
-
Identify Intel FPGA FlexLM license daemon installationSearch for FlexLM license manager binaries or services related to Intel FPGA software. Common binary names include 'lmgrd', 'lmstat', 'lmdown', or 'vendor daemons' for Intel. Check common installation paths such as C:\intelFPGA\ or /opt/intelfpga/ on Linux, or search for 'FlexLM' or 'lmgrd' using system search tools.Affected if Intel FPGA software with FlexLM license daemons is present on the system
-
Determine the FlexLM license daemon versionRun the license daemon binary with a version flag, such as 'lmgrd -v' or 'lmgrd -version', or check the file properties of the lmgrd.exe binary. On Windows, right-click the executable and view Properties > Details. On Linux, run './lmgrd -v' from the installation directory.Affected if The installed version is earlier than 11.19.5.0 (e.g., 11.18.x, 11.17.x, or earlier)
-
Inspect file permissions on license daemon executablesOn Windows, right-click the license daemon executable (lmgrd.exe) and go to Properties > Security > Permissions. Verify that non-privileged users do not have Write or Modify permissions. On Linux, run 'ls -la /path/to/lmgrd' and check that the file is not world-writable or group-writable by non-admin users.Affected if Non-privileged authenticated users have Write or Modify permissions to the license daemon executable files
-
Check service configuration and permissionsOn Windows, open Services (services.msc), locate any Intel FlexLM or license manager service, right-click > Properties > Log On tab. Verify the service runs under a restricted service account, not a privileged user. Also check the service binary path permissions in the registry or via 'sc qc' command.Affected if The license daemon service runs under a highly privileged account (such as LocalSystem or Domain Admin) and service binary is writable by low-privilege users
-
Verify inherited permission inheritance to child processesCheck if the license daemon spawns child processes and examine those processes' running context. Use Process Explorer or Task Manager to view the license daemon processes and their running user. If child processes run with elevated privileges while spawned by lower-privilege users, this indicates exploitable permission inheritance.Affected if Child processes spawned by the license daemon run with elevated privileges accessible to lower-privilege authenticated users
The environment is affected if Intel FPGA FlexLM license daemons version earlier than 11.19.5.0 are installed with overly permissive file or service permissions allowing non-privileged authenticated users to manipulate the daemon for privilege escalation.

dbcve · scoped11.19.5.0
Upgrade Intel FPGA software to version v11.19.5.0 or later which contains corrected permission handling in the FlexLM license daemon.
Intel FPGA Flexlm License Daemons v11.19.5.0
- 1. Identify all systems running Flexlm License Daemons for Intel FPGA software
- 2. Check current installed version of the Flexlm License Daemon
- 3. Download Intel FPGA software version v11.19.5.0 or later from the official Intel download portal
- 4. Back up existing Flexlm configuration files and license data
- 5. Stop the currently running Flexlm License Daemon service
- 6. Upgrade the Flexlm License Daemon to version 11.19.5.0 or later
- 7. Verify file permissions on license daemon files and directories are correctly set after upgrade
- 8. Restart the Flexlm License Daemon service
