CVE-2021-1114

System crash via kernel crypto use-after-free

Published Aug 11, 2021 · Updated Aug 3, 2024

Use-after-free in the kernel crypto node in NVIDIA Jetson Linux before 32.6.1 allows local users to crash the system. NVIDIA identifies the faulty lifetime handling only as a use-after-free and does not publish the allocation, release, or trigger path in the crypto node. Exploitation requires high local privileges and produces a complete denial of service without reported data disclosure or modification.
