An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\nTo exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.\nThe update addresses this vulnerability by correcting how the Windows kernel-mode driver handles objects in memory.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","base_score":7.0,"base_severity":"HIGH","attack_vector":"LOCAL","privileges_req":"LOW","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-787"],"in_kev":true,"kev_date_added":"2021-11-03","kev_ransomware":false,"epss_score":0.53878,"epss_percentile":0.99001,"cap_rule_version":"0.1.1","stage":"EXECUTION","req_access":"USER","req_vector":"LOCAL","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-10-09T03:16:29.560131+00:00","first_seen":"2020-05-21T23:15:12.070000+00:00","kev_first_seen":"2021-11-03T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["microsoft"],"products":["windows_10_1507","windows_10_1607","windows_10_1709","windows_10_1803","windows_10_1809","windows_10_1903","windows_10_1909","windows_7","windows_8.1","windows_rt_8.1","windows_server_1803","windows_server_1903","windows_server_1909","windows_server_2008","windows_server_2012","windows_server_2016","windows_server_2019"],"affected":[{"vendor":"microsoft","product":"windows_10_1507","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_10_1607","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_10_1709","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_10_1803","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_10_1809","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_10_1903","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_10_1909","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_7","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_8.1","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_rt_8.1","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_server_1803","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_server_1903","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_server_1909","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_server_2008","ranges":["all versions","r2"]},{"vendor":"microsoft","product":"windows_server_2012","ranges":["all versions","r2"]},{"vendor":"microsoft","product":"windows_server_2016","ranges":["all versions"]},{"vendor":"microsoft","product":"windows_server_2019","ranges":["all versions"]}]}
