CVE-2026-72007

VPU_NOC hang via ungated VC8000E power-up clocks

Published Aug 15, 2026 · Updated Aug 15, 2026

Denial of service in affected Linux kernels allows local users to hang the VPU_NOC during i.MX8MP VC8000E power cycling. The imx8m-blk-ctrl power-up path leaves the VC8000E and AXI clocks ungated as hardware deasserts reset, creating a timing window that can stall the power-down handshake. Reachability requires an i.MX8MP system that cycles the VC8000E or VPUMIX power domain; the bounded consequence is a VPU_NOC hang.
