Short explanation

In Samsung Semiconductor’s Exynos 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2600, 1580, 2500, 1680 and Modem 5123‑5410 models, processing a malformed RRC Reconfiguration message triggers an out‑of‑bounds access that leads to a denial‑of‑service (DoS) condition.

Why does it matter?

DoS can render mobile devices and network equipment unavailable, threatening service continuity.

What should be done?

  • Follow Samsung’s product‑security updates for a fix
  • Apply firmware updates when available
  • Validate and filter RFS messages at network edge
  • Implement network segmentation to limit impact
  • Monitor for any indicators of exploitation
