AI-suggested
Until a fix is applied, administrators should consider forcing SMB clients to disconnect and reconnect sessions to refresh group membership or apply any recommended workarounds from the vendor.
Description
A flaw was found in Samba. The smbd service daemon does not pick up group membership changes when re-authenticating an expired SMB session. This issue can expose file shares until clients disconnect and then connect again.
