The Linux kernel's ksmbd server is affected by a slab-use-after-free issue in the ksmbd smb2 session create function, caused by a race condition between ksmbd smb2 session create and ksmbd expire session. This issue can be exploited to impact the confidentiality, integrity, and availability of...

CVE-2021-20254

...

A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server which also serves protocols other than dnsserver will be restarted after a short delay but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate but many RPC services will not.
