CVE-2026-107159
Description
A flaw was found in miniupnpd. An unauthenticated attacker on the adjacent network can exploit this vulnerability to cause a Denial of Service (DoS) by crashing the service. By sending a specially crafted Simple Service Discovery Protocol (SSDP) search request with an invalid delay value, the attacker triggers a division-by-zero error in the packet processing routine. This causes the daemon to terminate unexpectedly, disrupting network discovery and Universal Plug and Play (UPnP) gateway services.
