The Falcon sensor for Mac, Linux, and Legacy Systems are not affected. \n\n\n\n\nThis vulnerability could expose an arbitrary file write to protected locations from an unprivileged context, potentially leading to local privilege escalation.\n\n\n\n\nThe CrowdStrike Laroux Malware Cleanup Tool, based off of the same feature in the CrowdStrike Falcon sensor for Windows, is also affected. An update for this tool is also available immediately.","published":"2026-09-15T18:17:21.000Z","lastModified":"2026-09-18T19:34:37.000Z","status":"Awaiting Analysis","sourceIdentifier":"13ddcd98-6f4a-40a8-8e24-29ca0aee4661","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-367"],"affected":[],"epss":{"score":0.00084,"percentile":0.00239,"date":"2026-11-07","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.08%).
