Local privilege escalation via kernel heap overflow
Published Mar 11, 2025 · Updated Feb 13, 2026
A heap-based buffer overflow in Microsoft's Windows Kernel Streaming Service Driver allows local users to elevate privileges. Microsoft identifies the affected locus only as Windows kernel-mode drivers and has not disclosed the input or operation that overruns heap memory. Exploitation requires low-privileged local access and grants elevated control over the affected system without user interaction.
