Local memory disclosure via out-of-bounds theme read
Published Jan 9, 2024 · Updated Jun 17, 2025
Out-of-bounds read in Windows Themes allows local users with low privileges to disclose memory contents on affected Windows systems. Microsoft identifies the affected component and weakness but has not disclosed the specific parser, function, or malformed input operation. Exploitation requires local access and high complexity; the documented consequence is confidential-memory disclosure without integrity or availability impact.
