In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Handle dml allocation failure to avoid crash [Why] In the case where a dml allocation fails for any reason, the current state's dml contexts would no longer be valid. Then subsequent calls dcstatecopyinternal would shallow copy invalid memory and if the new state was released, a double free would occur. [How] Reset dml pointers in newstate to NULL and avoid invalid pointer (cherry picked from commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)
