    Patch CVE-2024-35862
  62. Compensating control

    If you are able to avoid the affected code path while patching, skip SMB client sessions that are being teared down (status == SES_EXITING) so that smb2_is_network_name_deleted() does not operate on sessions in teardown and avoids the potential UAF described for CVE-2024-35862.
