If you possess a Samsung Galaxy smartphone or tablet, we strongly recommend that you halt whatever you’re doing and update your device immediately. The issue at hand is a significant security flaw on the Android side, identified as CVE-2025-21043. Discovered through WhatsApp, the source of the problem lies in an image-parsing library at libimagecodec.quram. This external software exhibits an out-of-bounds write vulnerability, leading to erratic memory allocation within the program. During this internal disorder, hackers can take advantage of the system’s writing function with harmful code.
Samsung has made it clear that vulnerabilities of this nature have previously been leveraged to compromise Galaxy devices, which underscores the urgency of updating without delay — even a brief hesitation could jeopardize any personal data saved on your device.
WhatsApp has also rolled out its own fix in reaction to the system breach. Even if you are using an iPhone or any other non-Galaxy device, this is undoubtedly the optimal moment to ensure your phone or tablet is operating with the latest OS and application updates.
