CVE-2026-64241

Medium

In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: teardown bugs and resource leaks Address several teardown issues and resource leaks in the driver's remove path and error handling: 1. Debounce clock reference leak: The debounce clock (bank->db_clk) is obtained using of_clk_get() which increments the clock's reference count, but clk_put() is never called. Register a devm action to cleanly release it on unbind. Note that of_clk_get(..., 1) remains necessary over devm_clk_get() because the DT binding does not define clock-names, precluding name-based lookup. 2. Unregistered chained IRQ handler: The chained IRQ handler is not disconnected in remove(). If a stray interrupt fires after the driver is removed, the kernel attempts to execute a stale handler, leading to a panic. Fix this by clearing the handler in remove(). 3. IRQ domain leak: The linear IRQ domain and its generic chips are allocated manually during probe but never removed. Remove the IRQ domain during driver teardown to free the associated generic chips and mappings. [Bartosz: don't emit an error message on devres allocation failure]
