CVE-2026-89504
High
Description
In the Linux kernel, the following vulnerability has been resolved: regulator: as3722_get_regulator_dt_data: fix premature of_node_put leaving dangling of_node pointer In as3722_get_regulator_dt_data(), of_get_child_by_name() acquires a reference on np, which is then assigned to pdev->dev.of_node. The function immediately calls of_node_put(np), releasing the reference and leaving pdev->dev.of_node as a dangling pointer. Remove the of_node_put(np) call to let the device hold the reference.
