Intel(R) Ethernet Network Controllers and…: Protection Mechanism Failure
CVE-2024-23499 is a high-severity protection mechanism failure vulnerability in Intel(R) Ethernet Network Controllers and Adapters E810 Series, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Intel(R) Ethernet Network Controllers and Adapters E810 Series versions: before version 28.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.53% 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 ethernet_network_controller_e810 to 28.3 or a later version.
- Update Ethernet 800 Series Controllers Driver to 28.3 or a later version.
- Read the advisory on intel.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
