The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:7338 advisory.
hw: cpu: AMD: Branch Type Confusion (non-retbleed) (CVE-2022-23825)
kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)
