CVE-2022-35191Network attack vector

Service interruption via crafted HTTP connection request

Published Aug 22, 2022 · Updated Jul 9, 2026

Denial of service in D-Link DSL-3782 firmware 1.01 allows remote attackers to interrupt service via a crafted HTTP connection request. Public records do not identify the request endpoint, malformed field, or resource-management operation that fails during processing. No authentication is required, but NVD records user interaction as required; the documented consequence is limited to loss of availability.
