When processing remote command execution IPC frames across the fabric, the receiving switch processes these commands at an elevated processing level without proper verification of transmitted parameters. This allows an attacker on a single fabric-connected switch to escalate privileges and execute arbitrary root commands locally or across other managed fabric members where remote execution functionality is enabled.","published_at":"2026-10-08T04:11:57.889000Z","last_modified_at":"2026-10-14T19:33:03.740000Z","cvss_v3_score":6.7,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":7.1,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-290"],"nvd_references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39163"],"vuln_status":"Analyzed","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":"2026-10-08T07:37:29.208922Z","updated_at":"2026-10-15T05:15:06.890595Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"H","value_label":"High"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"H","value_label":"High"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"broadcom","vendor_name":"Broadcom","product_slug":"fabric-operating-system","product_name":"fabric_operating_system","version_start":null,"version_start_inclusive":null,"version_end":"9.2.2d","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:o:broadcom:fabric_operating_system:*:*:*:*:*:*:*:*"},{"vendor_slug":"brocade","vendor_name":"Brocade","product_slug":"fabric-os","product_name":"Fabric OS","version_start":"0","version_start_inclusive":true,"version_end":"9.2.2d","version_end_inclusive":false,"cpe23_uri":"cve5:brocade:fabric-os:0:9.2.2d"},{"vendor_slug":"brocade","vendor_name":"Brocade","product_slug":"fabric-os","product_name":"Fabric OS","version_start":"10.0.0","version_start_inclusive":true,"version_end":"10.0.0a1","version_end_inclusive":true,"cpe23_uri":"cve5:brocade:fabric-os:10.0.0:10.0.0a1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://support.broadcom.com/external/content/SecurityAdvisories/0/39163","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-10-08T04:11:57.889000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-10-15T05:15:06.890595Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-10-15T05:15:06.890595Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-10-15T05:15:06.890595Z","label":"CVSS score revised","source":"nvd"}]}
