CVE-2026-90692

Name of the Vulnerable Software and Affected Versions D-Link DIR-878 version 120B05

Description A stack-based buffer overflow exists in the Dynamic DNS IPv6 Settings component. This issue occurs when the SetDynamicDNSIPv6Settings() function improperly handles the IPv6Address/Hostname argument, allowing a remote attacker to compromise the confidentiality, integrity, and availability of the protected information.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to the SetDynamicDNSIPv6Settings() function to minimize the risk of exploitation.
