CVE-2026-43460

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: rockchip-sfc: Fix double-free in remove() callback<br /> <br /> The driver uses devm_spi_register_controller() for registration, which<br /> automatically unregisters the controller via devm cleanup when the<br /> device is removed. The manual call to spi_unregister_controller() in<br /> the remove() callback can lead to a double-free.<br /> <br /> And to make sure controller is unregistered before DMA buffer is<br /> unmapped, switch to use spi_register_controller() in probe().
