An InfoSec professional successfully achieved root access on an Amazon Fire HD 10 (11th gen) to prevent unauthorized system shutdowns, a process costing $266.15 in AI model usage. After months of failed attempts using Claude—which eventually triggered cybersecurity safeguards—the author utilized a multi-model approach. Kimi K3 (Moonshot AI) identified a viable exploit path by analyzing the device's kernel against known vulnerabilities, specifically finding CVE-2022-38181, a use-after-free bug in the Arm Mali kernel driver that remained unpatched on the user's Fire OS 7.3.2.6 firmware. After Kimi K3 developed a toolkit and faced execution failures, GLM-5.2 (Z.ai) debugged the process, overcoming a false diagnosis regarding hardware-level cache coherency issues. Finally, GLM-5.3 completed the exploit in approximately eight hours by identifying a specific build shift in the kernel's memory offsets. By leveraging a GPU-to-DRAM write primitive, the model successfully flipped the SELinux enforcement bit and enabled a root shell. This allowed for the permanent removal of approximately 100 Amazon packages, including protected services with REBOOT and SHUTDOWN permissions, effectively reclaiming full ownership of the hardware.
