CVE-2014-8273 is a race condition in chipset BIOS write protection enforcement. When an attempt is made to enable BIOS writes despite a protection lock, an interrupt handler detects the condition and resets the write-enable state. The reset is not atomic with detection, creating a timing window in which an attacker can issue BIOS write operations before the write-enable bit is cleared.
