Vulnerability

Philips PIC iX 4.x listed as affected by two Windows DHCP vulnerabilities

MedDevice Cyber Staff · Jun 22 · 2 min read · Via Philips security advisory

Philips issued a notice on June 22, 2026 naming PIC iX 4.x as affected by two Microsoft Windows DHCP vulnerabilities, CVE-2026-44815 and CVE-2026-45602. Microsoft has released patches for both, and Philips says it is monitoring developments.

PIC iX is the central station for patient monitoring, so a Windows networking flaw on that host lands on the clinical network. Hospitals should not patch it themselves: Philips policy limits changes on its systems to Philips-authorized updates, which makes the validated patch timeline the real exposure window.

Remediation Desk

For ProvidersOperators, hospitals, and clinical engineering

Microsoft has patched CVE-2026-44815 and CVE-2026-45602. Operators of PIC iX 4.x should obtain the Philips-validated update rather than applying Microsoft patches directly, and limit DHCP exposure on the monitoring network until it is installed.

Request the validated update. Ask Philips service for the approved DHCP fix for PIC iX 4.x.
Segment the monitoring network. Keep PIC iX hosts on a dedicated VLAN with controlled DHCP services.
Watch for rogue DHCP. Enable DHCP snooping on switches serving the monitoring segment.

Fix the class in your product

The flaw is in the OS inside the controller, or a system past end of service still in the field. As the maker, own the embedded OS and server lifecycle as a safety obligation, design controllers to update in the field, and make every fault degrade to a defined safe state.

Own the OS lifecycle. Patch the OS and server components on a schedule with a tested delivery path.
Design for field update. And for planned replacement, so an unpatchable unit has a path off the network.
Degrade to safe. A fault drives a defined safe state, never an unexpected stop on a life-sustaining device.
