CVE-2024-26914 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/amd/display: fix incorrect mpc_combine array size

[why] MAX_SURFACES is per stream while MAX_PLANES is per asic. The mpc_combine is an array that records all the planes per asic. Therefore MAX_PLANES should be used as the array size. Using MAX_SURFACES causes array overflow when there are more than 3 planes.

[how] Use the MAX_PLANES for the mpc_combine array size.
