If ksmbd connection is\nreferenced when ksmbd server thread terminates, It will not be freed,\nbut conn->tcp_transport is freed. __smb2_lease_break_noti can be performed\nasynchronously when the connection is disconnected. __smb2_lease_break_noti\ncalls ksmbd_conn_write, which can cause use-after-free\nwhen conn->ksmbd_transport is already freed.\n\ud83d\udccf Published: 2025-05-01T13:07:15.741Z\n\ud83d\udccf Modified: 2025-05-02T06:16:21.642Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/1aec4d14cf81b7b3e7b69eb1cfa94144eed7138e\n2. https://git.kernel.org/stable/c/e59796fc80603bcd8569d4d2e10b213c1918edb4\n3. https://git.kernel.org/stable/c/21a4e47578d44c6b37c4fc4aba8ed7cc8dbb13de", "creation_timestamp": "2025-05-02T07:16:29.000000Z"}, {"uuid": "828e048a-dd3b-44d3-8e4d-d9c6f9b597dd", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2025-37777", "type": "seen", "source": "https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0316/", "content": "", "creation_timestamp": "2026-03-19T00:00:00.000000Z"}]}
