Null pointer dereference in submit_lookup_cmds() in drivers/gpu/drm/msm/msm_gem_submit.c

A NULL pointer dereference flaw was found in the Linux kernel's drivers/gpu/drm/msm/msm_gem_submit.c code in the submit_lookup_cmds function, which fails because it lacks a check of the return value of kmalloc(). This issue allows a local user to crash the system.
