Short explanation
CVE-2026-35494 causes an out‑of‑bounds write in Samsung Semiconductor’s Exynos 1280 and other Exynos modems during NAS packet processing in the baseband, leading to memory corruption and denial of service. Affected products include Exynos 1280, 2200, 1330, 1380, 2400, W920, W930 and Modem 5123/5300. No official patch status is confirmed, so updates should be closely monitored.
A denial‑of‑service can disrupt mobile and IoT communications, potentially causing widespread outages.
What should be done?
- Monitor Samsung security advisories and product updates
- Apply patches immediately when released
- Upgrade firmware to the latest version
- Inspect network traffic for anomalous NAS packets
- Deploy temporary mitigations such as packet filtering where feasible
