This patch is to fix issue caused by uninitialized local variable in Pei/Variable.c. In the fucntion CalculateHobVariableCacheSize(), the local variable VARIABLE_STORE_INFO StoreInfo is used without initialization. When the uninitialized variable is passed to CalculateAuthVarStorageSize() and GetNextVariablePtr(), the field StoreInfo->FtwLastWriteData might be a uninitialized non-zero value. Then the code execution will access the invalid address StoreInfo->FtwLastWriteData->TargetAddress. This might cause issue. So in this commit, the local variable VARIABLE_STORE_INFO StoreInfo is initialized by a ZeroMem() before use. Signed-off-by: Dun Tan <dun.tan@intel.com> |
