CVE-2020-25187 — Medtronic Mycarelink Smart Model 25000 Firmware security vulnerability

Critical CVSS 9.8

Medtronic MyCareLink Smart 25000 is vulnerable when an authenticated attacker runs a debug command, which can be sent to the patient reader and cause a heap overflow event within the MCL Smart Patient Reader software stack. The heap overflow could allow an attacker to remotely execute code on the MCL Smart Patient Reader, potentially leading to control of the device

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
