CVE-2026-8070Public exploit

Local physical-memory read/write via stale whitelist entries

Published May 29, 2026 · Updated May 29, 2026

Incorrect permission assignment in the Armoury Crate 6.4.12 and earlier AsIO3.sys driver allows local users to read and write physical memory. AsIO3.sys permits low-privileged callers to open its device, and its free-memory IOCTL releases pages without deleting their whitelist entries. The stale entries preserve read/write access after Windows recycles the pages, exposing or altering host physical memory without administrator rights.
