Answer in brief
CVE-2018-0175 records a High severity vulnerability in CVE Program Container. The current sources mark it as known exploited. The current feed maps n/a/Cisco IOS, IOS XE, and IOS XR (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
