CVE-2022-0636

System crash via undisclosed buffer overflow

Published Apr 22, 2022 · Updated Aug 2, 2024

Buffer overflow in Lenovo Thin Installer before 1.3.0039 allows local users to crash the system through crafted input. Lenovo identifies a classic buffer overflow but has not disclosed the affected function, input format, or unchecked copy operation. Exploitation requires low local privileges and user interaction, and the reported consequence is a system crash rather than data access or modification.
