Short explanation

Samsung Semiconductor’s Exynos 1080, 9110, Modem 5123, 5300 and 5400 chips contain an improper certificate validation flaw. An attacker can send a malicious IMS message to the device, potentially exposing information through the SIP message flow. Patch status is unverified in official sources and no active exploitation is reported.

Why does it matter?

Information leakage can compromise device confidentiality and create security gaps in communication infrastructures.

What should be done?

  • Monitor Samsung’s product security advisory for patch releases
  • Apply vendor‑provided fixes when available
  • Enforce strict certificate validation in IMS implementations
  • Restrict IMS traffic to trusted networks
  • Perform regular security testing of Exynos‑based devices
