Heap-memory disclosure via cryptography-provider out-of-bounds read
Published May 14, 2024 · Updated May 3, 2025
Out-of-bounds read in Windows Cryptographic Services allows local users to disclose small portions of heap memory through a crafted request. Microsoft states that the request reaches a vulnerable cryptography-provider function but does not identify the function or faulty bounds check. Exploitation requires local authentication and exposes memory without reported integrity or availability impact.
