CVE-2024-26797

In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Prevent potential buffer overflow in map_hw_resources Adds
a check in the map_hw_resources function to prevent a potential buffer
overflow. The function was accessing arrays using an index that could
potentially be greater than the size of the arrays, leading to a buffer
overflow. Adds a check to ensure that the index is within the bounds of the
arrays. If the index is out of bounds, an error message is printed and
break it will continue execution with just ignoring extra data early to
prevent the buffer overflow. Reported by smatch:
