Remote service interruption via NULL pointer dereference
Published Jul 11, 2023 · Updated Jan 1, 2025
NULL pointer dereference in Microsoft Windows PNRP allows remote attackers to interrupt affected systems through network traffic. Microsoft identifies the fault as a NULL pointer dereference but has not published the specific PNRP message field or code path that reaches the invalid dereference. Reachability requires IPv6-based PNRP communication, commonly over UDP port 3540, and successful exploitation interrupts service without reported data disclosure 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.
