System hang via incomplete PCIe resume sequence
Published Jan 11, 2025 · Updated May 11, 2026
A suspend/resume flaw in the Linux PCI i.MX6 controller allows local users to hang i.MX6QDL systems with connected PCIe devices. The controller's resume sequence modifies critical registers without reliably resetting the attached endpoint, leaving devices inaccessible when returning from D3hot. Exploitation requires local access, an i.MX6QDL platform, a connected PCIe device, and a suspend/resume cycle; the resulting fault interrupts the system.

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.
