How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream samba-devel package and not the samba-devel package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A flaw was found in Samba's internal DNS server where unauthenticated TKEY registration requests were added to the TKEY name cache before being rejected. A remote, unauthenticated attacker can exploit this behavior by sending a large number of TKEY requests with arbitrary names, exhausting the cache and evicting legitimate TKEY entries. This can prevent legitimate TSIG authentication for signed DNS queries, resulting in a denial of service.
