Urgent Security Alert: Samsung Phones Vulnerable to Remote Hijacking

September 16, 2025

Samsung Mobile users are now advised to promptly check for and install the latest security updates released in September 2025. The update addresses a notable vulnerability that could permit malicious actors to gain unauthorized access and control of their devices.

The core of the issue lies within a flaw identified as CVE-2025-21043, impacting the ‘libimagecodec.so‘ component. According to reports from Samsung, this vulnerability allows cybercriminals to exploit weaknesses in how images are processed, potentially executing arbitrary code on targeted devices.

What is ‘libimagecodec.so’ and Why Does it Matter?

Google Project Zero, a renowned team of security researchers, has detailed that ‘libimagecodec.so’ is a crucial, though closed-source, tool used by numerous third-party messaging applications – including the widely used WhatsApp – to decode and process images. Attackers could exploit this component to compromise a user’s phone.

The recently released patch for Samsung devices addresses the improper implementation of this tool, effectively mitigating the risk of such attacks. This improvement safeguards users against potential remote code execution exploits.

WhatsApp Played a Key role in Finding

The WhatsApp security team initially detected the potential exploitation of this security gap in August and privately reported it to both Samsung and Apple. This proactive disclosure allowed both companies to swiftly develop and deploy security patches.

While there have been no publicly reported instances of this vulnerability being actively exploited by hackers, Samsung confirmed they were informed of active exploitation attempts. This indicates that the threat is real, even if not yet widespread.

Although individual WhatsApp users may not be directly targeted, the existence of a tool capable of exploiting this vulnerability poses a broad risk, especially given WhatsApp’s massive user base of over 3 billion people worldwide.

is Your Messaging App secure?

Samsung’s security bulletin did not explicitly mention whether other third-party chat services are affected. However, industry analysts speculate that any application utilizing ‘libimagecodec.so’ could be potentially vulnerable, highlighting the need for widespread security awareness.

Apple swiftly responded to the threat, releasing a patch for its devices in late august. While the specifics of Appl
