Description OSIDB Bzimport 2026-07-28 14:02:27 UTC 
Parts of the DM_OP handling code assumes the caller has provided the
required number of buffers for the given operation without any checking
being done.  As a result, certain operations might access stack
rubble as structures are possibly uninitialized.
