In the Linux kernel, the following vulnerability has been resolved: MIPS: fw: Allow firmware to pass a empty env fw_getenv will use env entry to determine style of env, however it is legal for firmware to just pass a empty list. Check if first entry exist before running strchr to avoid null pointer dereference.
