Unauthenticated service interruption via out-of-bounds read
Published Jun 13, 2023 · Updated Jan 1, 2025
An out-of-bounds read in Microsoft Windows iSCSI Discovery Service allows remote attackers to interrupt affected systems over a network. Microsoft has not disclosed the specific parsing locus or the untrusted input that is read beyond its allocated boundary. No authentication or user interaction is required, and successful exploitation interrupts availability without reported data disclosure or modification.
