PatchTheCVECVE-2025-32003: Out-of-bounds read in the firmware for some 100GbE Intel(R) Ethernet Network Adapter E810 before version cvl f
CVE-2025-32003 is a medium-severity flaw (CVSS 6.5) affecting ethernet controller. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 inter
