What is CVE-2025-32003?
CVE-2025-32003 is a medium-severity denial of service vulnerability in 100GbE Intel(R) Ethernet Network Adapter E810, published on 10 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
