Revision 89a3c9f5b9f0bcaa9aea3e8b2a616fcaea9aad78 authored by Chuck Lever on 25 June 2020, 15:32:34 UTC, committed by Anna Schumaker on 26 June 2020, 12:45:23 UTC
@subbuf is an output parameter of xdr_buf_subsegment(). A survey of call sites shows that @subbuf is always uninitialized before xdr_buf_segment() is invoked by callers. There are some execution paths through xdr_buf_subsegment() that do not set all of the fields in @subbuf, leaving some pointer fields containing garbage addresses. Subsequent processing of that buffer then results in a page fault.
