CVE-2026-42487
HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses therefore needs...

CVE-2026-42487
CVE-2026-42487 concerns the Xen hypervisor’s handling of x86 HVM I/O port list traversal. The root cause stated in the sources is that traversal of the linked list used for guest I/O port accesses requires synchronization with updates to the translation/mapping (XEN_DOMCTL_ioport_mapping), but th...

x86 HVM I/O port list traversal
ISSUE DESCRIPTION HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses...
CVE-2026-3870
A buffer overflow vulnerability in the UPnP AddPortMapping command in Zyxel VMG4005-B50B firmware versions through 5.13ABRL.5.4C0 could allow an adjacent attacker to trigger a temporary denial-of-service DoS condition affecting the UPnP function of the affected device...
CVE-2026-7069
A security flaw has been discovered in D-Link DIR-825 up to 3.00b32. This impacts the function AddPortMapping of the file upnpsoap.c of the component miniupnpd. Performing a manipulation of the argument NewPortMappingDescription results in buffer overflow. The attack needs to be approached within...
CVE-2026-36603
Mercusys AC12G EU V1 router with firmware AC12GEUV1200909 exposes 15 of 18 UPnP IGD actions without authentication on port 1900, including AddPortMapping and GetExternalIPAddress. UPnP is enabled by default through the admin interface, allowing any unauthenticated LAN device to create arbitrary...

Zyxel VMG4005-B50B 安全漏洞
The Zyxel VMG4005-B50B is a VDSL2/ADSL2+ broadband modem produced by the Chinese company Zyxel. The firmware version 5.13ABRL.5.4C0 and earlier contain security vulnerabilities. These vulnerabilities stem from a buffer overflow in the UPnP AddPortMapping command, which could allow adjacent...
[SECURITY] Fedora 42 Update: miniupnpd-2.3.10-1.fc42
The MiniUPnP daemon is an UPnP IGD & PCP/NAT-PMP daemon for gateway routers. UPnP IGD & PCP/NAT-PMP are used to improve internet connectivity for devices behind a NAT router. Any peer to peer network application such as games, IM, etc. can benefit from a NAT router supporting UPnP IGD & PCP/NAT-P...
