Summary
In the Linux kernel, the following vulnerability has been resolved: fpga: region: fix use-after-free in child_regions_with_firmware() Move of_node_put(child_region) after the error print to avoid accessing freed memory when pr_err() references child_region. [ Yilun: Fix the Fixes tag ] A flaw was found in the Linux kernel FPGA region code. child_regions_with_firmware() drops a device-tree node reference and then logs that node, so the error path uses the node after it has been freed.
