If nameidx is crafted to point near the end of the buffer, these field accesses can read out-of-bounds before the bounds check at name_end > buf_end is performed. Add explicit bounds checks for entry pointers before accessing their fields. Use offsetof() to check that the start of the flexible array member (nameval/name) is within bounds, which ensures all preceding fields are safe to access.
