Local service interruption via out-of-bounds read
Published Apr 9, 2024 · Updated May 3, 2025
An out-of-bounds read in the Windows DWM Core Library on affected Windows releases allows local users to interrupt the service. Microsoft identifies the weakness class but has not disclosed the input, function, or bounds-checking error that reaches the invalid read. Low-privilege local access is required; the published vector supports availability loss, not direct disclosure or modification of data.
