CVE-2024-21806

Vulnerability

Analysis

This vulnerability resides in the Linux kernel mode driver for Intel Ethernet Network Controllers and Adapters E810 Series. An improper conditions check exists in the driver code, which can be triggered by a local attacker with system access [1].

Exploitation

Exploitation requires the attacker to have authenticated local access to the system. The attack vector is local, meaning the attacker must be able to execute code or interact with the driver on the target machine. No special privileges beyond standard user authentication are mentioned, and the vulnerability can be exploited without physical access [1].

Impact

A successful exploit enables an attacker to cause a denial of service condition on the affected system. This could manifest as system instability, driver crashes, or unavailability of network functions provided by the controller [1].

Mitigation

Intel has released driver version 28.3 which addresses this issue. Users are advised to update the driver for the E810 series controllers to this or a later version to mitigate the vulnerability [1].
