A malicious actor with local administrative privileges on a virtual machine may be able to exploit this issue to crash the virtual machine's vmx process leading to a denial of service condition or execute code on the hypervisor from a virtual machine. Additional conditions beyond the attacker's control must be present for exploitation to be possible.","published_at":"2020-06-25T14:43:59Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://www.vmware.com/security/advisories/VMSA-2020-0015.html","https://www.zerodayinitiative.com/advisories/ZDI-20-781/"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:14:20.820317Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"vmware","vendor_name":"VMware","product_slug":"fusion","product_name":"Fusion","version_start":"11.x before 11.5.5","version_start_inclusive":true,"version_end":"11.x before 11.5.5","version_end_inclusive":true,"cpe23_uri":"cve5:vmware:fusion:11.x before 11.5.5:11.x before 11.5.5"},{"vendor_slug":"vmware","vendor_name":"VMware","product_slug":"vmware-esxi","product_name":"VMware ESXi","version_start":"7.0 before ESXi_7.0.0-1.20.16321839","version_start_inclusive":true,"version_end":"7.0 before ESXi_7.0.0-1.20.16321839","version_end_inclusive":true,"cpe23_uri":"cve5:vmware:vmware-esxi:7.0 before ESXi_7.0.0-1.20.16321839:7.0 before ESXi_7.0.0-1.20.16321839"},{"vendor_slug":"vmware","vendor_name":"VMware","product_slug":"vmware-esxi","product_name":"VMware ESXi","version_start":"6.7 before ESXi670-202004101-SG","version_start_inclusive":true,"version_end":"6.7 before ESXi670-202004101-SG","version_end_inclusive":true,"cpe23_uri":"cve5:vmware:vmware-esxi:6.7 before ESXi670-202004101-SG:6.7 before ESXi670-202004101-SG"},{"vendor_slug":"vmware","vendor_name":"VMware","product_slug":"vmware-esxi","product_name":"VMware ESXi","version_start":"6.5 before ESXi650-202005401-SG","version_start_inclusive":true,"version_end":"6.5 before ESXi650-202005401-SG","version_end_inclusive":true,"cpe23_uri":"cve5:vmware:vmware-esxi:6.5 before ESXi650-202005401-SG:6.5 before ESXi650-202005401-SG"},{"vendor_slug":"vmware","vendor_name":"VMware","product_slug":"workstation","product_name":"Workstation","version_start":"15.x before 15.5.5","version_start_inclusive":true,"version_end":"15.x before 15.5.5","version_end_inclusive":true,"cpe23_uri":"cve5:vmware:workstation:15.x before 15.5.5:15.x before 15.5.5"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.vmware.com/security/advisories/VMSA-2020-0015.html","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://www.zerodayinitiative.com/advisories/ZDI-20-781/","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2020-06-25T14:43:59Z","label":"CVE published","source":null}]}
