Host interruption via LockHandle NULL dereference
Published Sep 22, 2025 · Updated Sep 22, 2025
NULL pointer dereference in Graphics DDK 1.17 RTM, 1.18 RTM, and 23.2 RTM through 25.1 RTM1 allows local users to interrupt the host. On a bridge entry, LockHandle dereferences a NULL pointer when a non-privileged process misuses a driver connection through improper GPU system calls. The attack requires local execution and GPU-driver access; the resulting kernel exception disrupts availability without reported data exposure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.17 RTM
- Affected versionversion=1.18 RTM
- Affected versionversion=23.2 RTM <=25.1 RTM1
