Do you use WhatsApp on a Samsung phone? Then you need to act - Samsung Urges Users to Update: Critical WhatsApp Vulnerability Patched

Samsung has addressed a critical security vulnerability affecting millions of its smartphones. The issue, which exploits WhatsApp Web as an entry point for hackers, allows remote code execution via a manipulated image file. Users are urged to update their devices and WhatsApp Web immediately.

The vulnerability, identified as CVE-2025-21043, impacts Samsung smartphones running Android 13 and later versions. This includes nearly all Samsung devices sold in the last five years. The flaw lies in a closed-source image processing library, enabling hackers to remotely execute malicious code.

Samsung has rolled out a patch as part of its major OneUI 8 update for newer flagship models like the S25. For older flagship devices such as the S23, the September security patch closes the vulnerability. WhatsApp has informed partners like Apple and Samsung about the issue, with Apple already closing it on their end.

To safeguard their devices, Samsung users should promptly update their operating system and WhatsApp Web to the latest versions. This will ensure the patch for the critical vulnerability is installed, protecting their smartphones from potential remote attacks.
