Case 1 - Within DuplicateFid() & DuplicateFe(): The call to AllocateCopyPool() may return NULL. Add ASSERTs as checks. Case 2 - Within UdfRead(): Add ASSERT to ensure 'NewFileEntryData' returned from FindFileEntry() will not be NULL pointer. Case 3 - Within GetAllocationDescriptorLsn(): The return value of 'GetPdFromLongAd (Volume, ParentIcb)' may be NULL, and it will be passed into function GetShortAdLsn() which will dereference it. Add ASSERT in GetShortAdLsn() as check. Case 4 - Within ReadFile(): Add ASSERT to ensure 'Data' returned from GetAedAdsData() will not be NULL pointer. Case 5 - Within InternalFindFile(): If both 'Parent->FileIdentifierDesc' and 'Icb' are NULL, then possible NULL pointer dereference will happen in ReadDirectoryEntry(). Add additional check to resolve.
