#exploit

Nebula Security disclosed a remote root exploit chain targeting all Android versions, combining a Firefox browser vulnerability (affecting version 151.0.2 and earlier) and a 15-year-old Linux kernel flaw (CVE-2026-43499, GhostLock), with proof-of-concept code released on GitHub. This exploit chain allows attackers to gain persistent root access on any Android device by simply tricking a user into clicking a malicious link, posing a severe security risk to billions of users and potentially leading to widespread exploitation. The attack leverages a remote code execution vulnerability in Mozilla Firefox and the GhostLock kernel flaw for privilege escalation, enabling attackers to execute arbitrary commands via ADB and implant files for persistent control.
