If an error occurs subsequently (eg, ksmbd_iov_pin_rsp fails)\nor a scavenger accesses the file, it leads to a use-after-free when\naccessing fp properties (eg fp->create_time).\n\nMove the single put to the end of the function below err_out2 so fp\nstays valid until smb2_open returns.","published":"2026-06-24T17:17:12.000Z","lastModified":"2026-09-14T12:17:43.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":["linux/linux kernel"],"epss":{"score":0.00444,"percentile":0.38397,"date":"2026-10-26","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 (0.44%).
