Android phone users are urged to stay vigilant and ensure their settings are updated following the discovery of a critical bug within the widely used operating system. Security experts have raised concerns after the bug, which has now been fixed by Google, was identified as a zero-day threat, indicating it was already being exploited by hackers.
Adam Boynton, Senior Security Strategy Manager EMEIA at Jamf, emphasized the importance of promptly updating Android devices in response to the recent security bulletin. The bulletin addressed an actively exploited vulnerability, CVE-2025-27363, underscoring the need for immediate action from all Android users.
While Google routinely releases monthly patches to address minor issues, the severity of some vulnerabilities necessitates swift action from phone users to ensure their devices are protected. Boynton highlighted that the fixed bug pertained to an out-of-bounds memory vulnerability in the FreeType software, a critical component of Android devices responsible for font rendering and therefore a prime target for cybercriminals.
The nature of this exploit allows attackers to potentially take control of the entire system without elevated privileges. Despite being a targeted attack primarily affecting high-value individuals, all Android users are strongly advised to update their operating systems due to the bug being exploited since March. The zero-click nature of the vulnerability enables criminals to exploit it without user detection.
Google typically rolls out updates initially to Pixel devices, with other manufacturers like Samsung, OnePlus, and Honor following suit shortly thereafter. Regardless of the phone model, it is crucial for users to visit their settings menu promptly to ensure their devices are fully updated and secure.
