Kernel-address disclosure via exposed scanner function
Published Jun 9, 2022 · Updated Aug 3, 2024
Information disclosure in Trend Micro Security 2021 and 2022 allows local users to obtain kernel addresses through the NCIE Scanner module. The module exposes a dangerous function to unprivileged callers, returning sensitive kernel address information. Low-privileged code execution is required; the disclosure can be chained with other flaws to run code in kernel context.
