Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of kernel installed on the remote host is prior to 5.10.234-225.917. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2025-085 advisory.

Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)
