Privilege escalation or crash via binary deserialization
Published Jul 24, 2025 · Updated Mar 27, 2026
Deserialization in Medtronic MyCareLink Patient Monitor models 24950 and 24952 before June 25, 2025 allows local users to gain privileges. The internal service deserializes an attacker-crafted binary payload, allowing the payload to crash the service or elevate privileges. Exploitation requires physical tampering, local low-privileged access, and high-complexity conditions; consequences include a service crash or elevated control of the monitor.
