DNVN - Samsung has released an emergency update for all eligible Galaxy phones after it was notified of a serious security vulnerability that could allow hackers to remotely exploit phones and take full control.

The security vulnerability in question is identified as CVE-2025-21043. It exists in the image processing and analysis library built into Samsung Galaxy devices. Many popular apps like WhatsApp use this library to display images.

According to a warning from the US Cybersecurity and Infrastructure Security Agency (CISA), this vulnerability "allows an attacker to execute arbitrary code remotely." In other words, hackers can install malicious code and take control of a user's device without direct interaction or tricking the user into clicking any links.

The severity of the vulnerability has forced the US government to issue a new warning, requiring federal employees to update or stop using Galaxy phones by October 23.

Brian Thornton, a security expert at Zimperium, said the vulnerability "shows that attackers are moving to mobile devices as a rapid attack vector." He also pointed out that a closed-source image library has created widespread risks on Samsung devices and apps that depend on it.

Samsung said the bug was fixed in the September security update. However, the Galaxy maker just released the October update.

Cybersecurity experts recommend that all Galaxy owners install this new update as soon as it's available, even if they've already applied September's critical bug fix. The latest OS will contain the latest fixes and ensure your phone is protected.

Experts advise users not to delay software updates thinking "the device is still working normally", because these patches play a crucial role in fixing security vulnerabilities that users are not aware of.
