Service interruption and kernel memory leak via IOCTL
Published Jul 11, 2024 · Updated Aug 1, 2024
Out-of-bounds write in Foxboro.sys in EcoStruxure Foxboro DCS Core Control Services 9.8 and earlier allows local users to interrupt service. The driver processes attacker-controlled input from a crafted IOCTL request and writes outside the intended buffer; the vendor has not disclosed the affected handler or validation error. Local low-privileged access and no user interaction are required, and exploitation can also leak kernel memory.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
