Doc Text:
A flaw was found in the Linux kernel's amdgpu graphics driver. The driver fails to limit the nesting depth during the execution of ATOM command tables, allowing unbounded recursion. A local user could trigger excessive recursion to cause a kernel stack overflow, leading to a system crash and Denial of Service (DoS).
