Mô tả

In the Linux kernel, the following vulnerability has been resolved:

drm/i915/dmc: Add sanity check for DMC load address

For DMC firmware header version 3, the firmware load address is stored
in dmc_info->start_mmioaddr and later used by dmc_load_program().

Unlike the MMIO address table, the firmware load address is not
validated. Add a sanity check to ensure it is within the valid range.

BSpec: 69671, 68378
(cherry picked from commit 5e47ee5c76ca9becde8df4ad5202845b7ffcbc4c)
