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