Samsung mobile devices that use certain Exynos chipsets are affected by a vulnerability that could allow remote code execution if exploited.

The vulnerability is a buffer overflow issue found in the 5G multimedia messaging codec in Exynos 850, 980, 1080, 1280 and 2200 chipsets as well as their modem components. When decoding an extended emergency number list, insufficient validation of user-supplied parameters could allow a heap-based overflow to occur.

In layman’s terms, this means a hacker could potentially craft a malicious multimedia message that, when decoded by a vulnerable Samsung device, could overwrite the device’s memory and execute code of the attacker’s choosing. This would give the attacker full control of the targeted phone or tablet.

If exploited remotely over a 5G connection, this vulnerability could allow a hacker to silently take over Samsung devices without the user even knowing. They could then access photos, messages, and sensitive data stored on the device.

The best way for Samsung users to protect themselves is to keep their devices updated with the latest software patches. Over-the-air updates from Samsung directly address security issues and are important to install right away. You should also be cautious of unknown links and attachments in multimedia messages from untrusted sources.
