Elevated-privilege code execution via Cboot buffer overflow
Published Apr 27, 2022 · Updated Aug 3, 2024
Memory corruption in NVIDIA Jetson Linux before 32.7.2 allows local users with elevated privileges to execute code through Cboot input. The tegrabl_cbo.c code processes untrusted data without sufficient validation, allowing the data to overflow a memory buffer. Exploitation requires elevated local privileges and can execute code, alter data, expose limited information, or interrupt the device.
