What is CVE-2026-90152?

In the Linux kernel, the following vulnerability has been resolved:

smb/server: fix session leak in ksmbd_session_register()

See the procedure below:

smb2_sess_setup ksmbd_smb2_session_create __session_create atomic_set(&sess->refcnt, 2) hash_add(sessions_table, &sess->hlist, sess->id) ksmbd_session_register xa_store(&conn->sessions, sess->id, sess) // fail ksmbd_user_session_put atomic_dec(&sess->refcnt) // refcnt is 1, session is not freed
