Remote code execution via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 9, 2026
Out-of-bounds read in Microsoft Windows Event Logging Service allows remote attackers to execute code over a network. The service reads beyond the bounds of an intended memory buffer, but Microsoft has not disclosed the affected routine or crafted input. Exploitation requires user interaction and can run attacker-controlled code with the service's access.
