CVE-2026-58218 2 Redhat, Samba 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-07-30 5.3 Medium
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.
