description
Affected Samsung Semiconductor Exynos processors and modems mishandle a length field in NAS messages, which can cause memory corruption. An attacker must be able to cause an affected device or modem to process a malformed NAS message; the evidence does not specify further access or authentication preconditions.
mitigation
Install the September 2026 security update provided for affected Exynos-based devices and modem products. Obtain and apply current device, modem, and carrier updates where applicable.

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.
