CVE-2024-22390

Vulnerability

Overview

CVE-2024-22390 describes an improper input validation vulnerability in the firmware of certain Intel(R) FPGA products. The issue exists in firmware versions prior to 2.9.1, where insufficient validation of user-supplied input could lead to a denial of service (DoS) condition [1].

Attack

Scenario

According to the Intel security advisory, an authenticated user with adjacent network access could exploit this flaw. The attack requires the attacker to have valid credentials and be on the same network segment as the vulnerable device. No special privileges beyond standard user authentication are necessary, and no user interaction is required [1].

Impact

Successful exploitation can cause the FPGA firmware to become unresponsive or crash, resulting in a denial of service. This can disrupt operations relying on the affected FPGA hardware, potentially leading to system downtime or reduced availability [1].

Remediation

The vulnerability is fixed in Intel FPGA firmware version 2.9.1 or later. Intel recommends updating affected firmware to the latest version. No workarounds are provided for unpatched versions, making updating the primary mitigation [1].
