Authenticated system crash via CryptoAPI null dereference
Published Jun 13, 2023 · Updated Jan 1, 2025
Denial of service in Microsoft Windows CryptoAPI allows remote authenticated users to crash an affected system through network input. Microsoft identifies a NULL pointer dereference in CryptoAPI but has not disclosed the affected function, input format, or dereference path. Exploitation requires low-privileged authentication and no user interaction; the bounded impact is a system crash without reported data disclosure or modification.
