System crash via kernel out-of-bounds read
Published Dec 12, 2023 · Updated May 22, 2025
An out-of-bounds read in the Windows kernel in Windows 11 22H2, 22H3, and 23H2 allows local users to crash the system via local input. Microsoft has not published the affected kernel code path or the malformed input that triggers the invalid read. Exploitation requires local access and user interaction, and the documented consequence is loss of system availability rather than data access 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.
