In the Linux kernel, the following vulnerability has been resolved: fpga:
region: add owner module and take its refcount The current implementation
of the fpga region assumes that the low-level module registers a driver for
the parent device and uses its owner pointer to take the module’s refcount.
This approach is problematic since it can lead to a null pointer
dereference while attempting to get the region during programming if the
parent device does not have a driver. To address this problem, add a module
owner pointer to the fpga_region struct and use it to take the module’s
refcount. Modify the functions for registering a region to take an
additional owner module parameter and rename them to avoid conflicts. Use
the old function names for helper macros that automatically set the module
that registers the region as the owner. This ensures compatibility with
existing low-level control modules and reduces the chances of registering a
region without setting the owner. Also, update the documentation to keep it
consistent with the new interface for registering an fpga region.
