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.
