Vulnerability from gsd

Details
In the Linux kernel, the following vulnerability has been resolved: spmi: mediatek: Fix UAF on device remove The pmif driver data that contains the clocks is allocated along with spmi_controller. On device remove, spmi_controller will be freed first, and then devres , including the clocks, will be cleanup. This leads to UAF because putting the clocks will access the clocks in the pmif driver data, which is already freed along with spmi_controller. This can be reproduced by enabling DEBUG_TEST_DRIVER_REMOVE and building the kernel with KASAN. Fix the UAF issue by using unmanaged clk_bulk_get() and putting the clocks before freeing spmi_controller.
