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 spmicontroller. On device remove, spmicontroller 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 DEBUGTESTDRIVER_REMOVE and building the kernel with KASAN.

Fix the UAF issue by using unmanaged clkbulkget() and putting the clocks before freeing spmi_controller.
