Code execution via CBoot ext4 integer overflow
Published Apr 27, 2022 · Updated Aug 3, 2024
Integer overflow in NVIDIA Jetson AGX Xavier and Xavier NX before 32.7.2 allows local users to execute code across components. The CBoot ext4_read_file function insufficiently validates untrusted EXT4 file data before an integer operation, allowing the result to overflow. Exploitation requires high local privileges and can escalate privileges, execute code, interrupt service, or affect data confidentiality and integrity.
