CVE-2022-36508Public exploit

Memory corruption via SetAPInfoById stack overflow

Published Aug 25, 2022 · Updated Jun 17, 2025

Stack overflow in SetAPInfoById in H3C Magic NX18 Plus NX18PV100R003 allows local users to corrupt process memory via crafted input. The public record identifies SetAPInfoById as the overflow locus but does not disclose the parameter, copy operation, or affected buffer. The low-privileged local-access gate limits reachability, and public evidence establishes memory corruption rather than stable code execution.
