BIOS implementations fail to properly set UEFI write protections after waking from sleep mode

Overview Multiple BIOS implementations fail to properly set write protections after waking from sleep, leading to the possibility of an arbitrary BIOS image reflash. Description According to Cornwell, Butterworth, Kovah, and Kallenberg, who reported the issue affecting certain Dell client systems...

Intel BIOS locking mechanism contains race condition that enables write protection bypass

Overview A race condition exists in Intel chipsets that rely solely on the BIOSCNTL.BIOSWE and BIOSCNTL.BLE bits as a BIOS write locking mechanism. Successful exploitation of this vulnerability may result in a bypass of this locking mechanism. Description CWE-362: Concurrent Execution using Share...
