  "title": "ksmbd: defer destroy_previous_session() until after NTLM authentication",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: defer destroy_previous_session() until after NTLM authentication  In ntlm_authenticate(), destroy_previous_session() is called using a user pointer resolved from the client-supplied NTLM blob username field before the NTLMv2 response is validated. An authenticated attacker can set the NTLM blob username to match a victim account and set PreviousSessionId to the victim\u0027s session ID; destroy_previous_session() destroys the victim\u0027s session while ksmbd_decode_ntlmssp_auth_blob() subsequently rejects the request with -EPERM.  Move destroy_previous_session() and the prev_id assignment to after ksmbd_decode_ntlmssp_auth_blob() returns success and use sess-\u003Euser rather than the pre-authentication lookup result. This matches the ordering already used by krb5_authenticate(), where destroy_previous_session() is called only after ksmbd_krb5_authenticate() returns success.",
