Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: fix incorrect mpc_combine array size<br /> <br /> [why]<br /> MAX_SURFACES is per stream, while MAX_PLANES is per asic. The<br /> mpc_combine is an array that records all the planes per asic. Therefore<br /> MAX_PLANES should be used as the array size. Using MAX_SURFACES causes<br /> array overflow when there are more than 3 planes.<br /> <br /> [how]<br /> Use the MAX_PLANES for the mpc_combine array size.
