CVE-2025-62627

Guest memory disclosure via untrusted pointer dereference

Published May 13, 2026 · Updated May 13, 2026

Untrusted pointer dereference in the ionic cloud driver for VMware ESXi 8.x and 9.x allows guest OS users to read kernel or co-located VM memory. AMD identifies the vulnerable operation but has not published the affected function, pointer source, or omitted validation. Exploitation requires an unprivileged VM on a host using an AMD-Pensando DPU; the availability failure mode remains undisclosed.
