Re: [U-Boot] [U-Boot,1/1] env: avoid possible NULL pointer access

env_attr_lookup call env_attr_walk with callback = regex_callback.

In env_attr_walk attributes = strchr(entry_cpy, ENV_ATTR_SEP) will return NULL if ENV_ATTR_SEP is not found.

In the aftermath regex_callback may call strlen(attributes) with a NULL value which will lead to a failure.

The problem was indicated by scan-clam.
