CVE-2025-71185Hinoki check available

Local service interruption via DMA device-reference leak

Published Jan 31, 2026 · Updated Jan 31, 2026

Resource leak in the TI DMA crossbar driver in Linux Kernel allows local users to interrupt service through AM335x route allocations. ti_am335x_xbar_route_allocate() obtains a platform-device reference with of_find_device_by_node() but previously returned without calling put_device() on that reference. Exploitation requires local low-privileged access and repeated route allocation on hardware using the AM335x EDMA crossbar; retained references can exhaust kernel resources and interrupt service.
