CVE-2026-36602: n/a
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 discloses kernel memory layout via the UPnP GetStatusInfo action. An unauthenticated attacker on the adjacent network can obtain a raw MIPS KSEG0 kernel pointer, revealing kernel memory layout and aiding further exploitation.
AI Analysis
Technical Summary
The Mercusys AC12G (EU) V1 router running firmware AC12G(EU)_V1_200909 is vulnerable to an information disclosure issue through the UPnP GetStatusInfo action. This vulnerability allows an unauthenticated attacker on the adjacent network to retrieve a raw MIPS KSEG0 kernel pointer, revealing the kernel memory layout. Such disclosure can facilitate subsequent attacks by providing insight into the kernel's memory organization. The vulnerability is classified under CWE-200 (Information Exposure). No patch or official remediation has been indicated as of the published date.
Potential Impact
The vulnerability results in limited confidentiality impact by exposing kernel memory layout information to unauthenticated attackers on the adjacent network. There is no direct impact on integrity or availability. The disclosed kernel pointer can assist attackers in crafting further exploits against the device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the UPnP service from untrusted networks and limit network adjacency to trusted devices only.
