This patch series adds a failure check after calling grub_strdup()/strdup. Missing a failure check after calling grub_strdup() can lead to undefined behavior. If it fails and returns NULL, subsequent dereferencing or writing to the pointer will likely result in a runtime error such as a segmentation fault.
