description
The flaw affects the listed Exynos processors, modems, and wearable platforms. An attacker able to cause a vulnerable device to process NAS DLTransport messages may crash the baseband.
mitigation
Install the July 2026 security update for affected devices and Exynos-based products. Prioritize devices that may process untrusted cellular-network traffic.
fixed in July 2026

exploit
no
automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
contextual
auth requiredWhether an attacker needs an account first, based on the CVSS vector's Privileges Required.
