Doc Text:
A memory leak was found in the Linux kernel's AMD display driver in the clock source initialization logic. When the initialization function encounters an error in its final return path, allocated memory for the clk_src structure is not freed before returning NULL. This results in leaked memory that accumulates with repeated initialization attempts, leading to resource exhaustion and denial of service.
