CVE-2022-28197

Local code execution via ext4_mount integer overflow

Published Apr 27, 2022 · Updated Aug 3, 2024

Integer overflow in Cboot ext4_mount in NVIDIA Jetson Linux before 32.7.2 allows local users with high privileges to execute code. The function insufficiently validates untrusted ext4 filesystem data before an integer calculation; NVIDIA has not disclosed the affected field or operation. Reaching the flaw requires highly privileged local access and high complexity; exploitation also causes limited data exposure, modification, or service interruption, whose failure mode NVIDIA does not specify.
