The recv variable in sandbox_tpm2_fill_buf() is a pointer on a pointer of a char array. It means accessing *recv is the char array pointer itself while **recv is the first character of that array. There is no need for such indirection here, so simplify the code. Simplifying things will make the last assignment right: "*recv = NULL" is now correct. The issue has been found by the following Coverity Scan report: CID 183371: Incorrect expression (UNUSED_VALUE) Assigning value "4UL" to "*recv" here, but that stored value is overwritten before it can be used. 232 *recv += sizeof(rc); 233 234 /* Add trailing \0 */ 235 *recv = NULL; While at simplifying things, use '\0' instead of NULL when adding an empty char at the end of the buffer.
