Cybersecurity firm Nebula recently unveiled a demonstration video exposing a critical kernel-level vulnerability and remote privilege escalation exploit within the Android ecosystem. This sophisticated exploit chain weaponizes a browser vulnerability present in Firefox version 151.0.2 and its predecessors, alongside a 15-year-old flaw lingering within the Linux kernel. By chaining these security flaws, the research team engineered an exploit mechanism capable of automatically root-compromising a device and escalating privileges upon a single user interaction with a malicious URL.
