[REJECTED CVE] A secure boot bypass vulnerability was found in EDK2 due to the lack of proper return value checks in the GetEfiGlobalVariable2() function. The API may fail if functions like AllocatePool() or gRT->GetVariable() fail. Without verifying the return value, an attacker could cause the API to fail, potentially bypassing secure boot. This issue occurs in functions like DxeImageVerificationHandler, where the return value is not checked.
Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was in a CNA pool that was not assigned to any issues during 2019. Notes: none.
