Intel(R) FPGA products: Improper Access Control
CVE-2024-25576 is a high-severity improper access control vulnerability in Intel(R) FPGA products, with a CVSS 3.1 base score of 7.9 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, without any action from a user. Affected Intel(R) FPGA products versions: before version 24.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update agilex_7_fpga_f-series_019_firmware to 24.1 or a later version.
- Update Agilex 7 Fpga Firmware to 24.1 or a later version.
- Read the advisory on intel.com for workarounds and exact fixed builds.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Intel(R) FPGA products | Intel(R) FPGA products | before version 24.1 | Not stated |
| Intel | agilex_7_fpga_f-series_019_firmware | before 24.1 | 24.1 |
| Intel | Agilex 7 Fpga Firmware | before 24.1 | 24.1 |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.
How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required
- HighAdministrator-level access is required first.
- User interaction

Official description
improper access control in firmware for some Intel(R) FPGA products before version 24.1 may allow a privileged user to enable escalation of privilege via local access.

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
