Doc Text:
A memory leak flaw was found in the Linux kernel's Intel i915 graphics driver in the selftest page allocation logic. A local user can trigger this issue when running i915 selftests and the fake_get_pages function encounters errors, causing the function to return without freeing previously allocated memory. This results in a permanent memory leak leading to resource exhaustion and denial of service.
