MEDIUM 4.9EPSS 0.75%
Does this matter?
Lower severity and a low EPSS score (0.75%). Track it; it rarely justifies an emergency change on its own.
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.
