Exploiting this vulnerability causes the vCMPd process on the adjacent VCMP guest to restart and produce a core file. This issue is only exploitable on a VCMP guest which is operating in \"host-only\" or \"bridged\" mode. VCMP guests which are \"isolated\" are not impacted by this issue and do not provide mechanism to exploit the vulnerability. Guests which are deployed in \"Appliance Mode\" may be impacted however the exploit is not possible from an Appliance Mode guest. To exploit this vulnerability root access on a guest system deployed as \"host-only\" or \"bridged\" mode is required.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:H","score":5.4},"cwes":[],"references":["http://www.securitytracker.com/id/1040797","https://support.f5.com/csp/article/K03165684","http://www.securitytracker.com/id/1040797","https://support.f5.com/csp/article/K03165684"],"products":["f5:big-ip_access_policy_manager","f5:big-ip_advanced_firewall_manager","f5:big-ip_analytics","f5:big-ip_application_acceleration_manager","f5:big-ip_application_security_manager","f5:big-ip_domain_name_system","f5:big-ip_edge_gateway","f5:big-ip_global_traffic_manager","f5:big-ip_link_controller","f5:big-ip_local_traffic_manager","f5:big-ip_policy_enforcement_manager","f5:big-ip_webaccelerator","f5:big-ip_websafe"],"source":"nvd","synced_at":"2026-10-19T20:50:40.212176939+00:00"},"epss":{"cve":"CVE-2018-5518","score":0.00404,"percentile":0.34696,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
