AI-suggested
- Immediately verify the firmware version of Intel 100GbE Ethernet Network Adapter E810 devices and upgrade to firmware version cvl fw 1.7.6 or later and cpk 1.3.7 or later as soon as Intel releases official patches.
- Restrict network access to management interfaces and authenticated users to trusted personnel only, employing strong authentication mechanisms and network segmentation to limit exposure.
- Monitor network traffic and adapter behavior for signs of abnormal activity or crashes that could indicate exploitation attempts.
- Implement strict access controls and logging on systems using these adapters to detect and respond to suspicious authenticated network activity.
- Coordinate with Intel support and hardware vendors to receive timely updates and advisories.
- Consider deploying network-level protections such as intrusion detection/prevention systems (IDS/IPS) tuned to detect anomalous traffic patterns targeting these adapters.
- Conduct regular security audits and firmware inventory to ensure compliance with patching policies.
- Prepare incident response plans specifically addressing denial of service scenarios involving network hardware failures.
Description
Out-of-bounds read in the firmware for some 100GbE Intel(R) Ethernet Network Adapter E810 before version cvl fw 1.7.6, cpk 1.3.7 within Ring 0: Bare Metal OS may allow a denial of service. Network adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via network access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
