: This may indicate a physical fault with the processor (often logged as CPU0000 or CPU0704 ).
UEFI0078 is part of a growing trend of firmware vulnerabilities categorized by security researchers (like those at ESET). It highlights the risks associated with proprietary UEFI drivers added by hardware vendors on top of the standard UEFI specification. These custom drivers often introduce attack surfaces that are less audited than the core platform code. uefi0078
The flaw resides within a custom UEFI driver developed by Lenovo. Due to insufficient validation of input data, the vulnerability allows an attacker with administrative privileges to trigger a buffer overflow, potentially leading to arbitrary code execution during the boot process. : This may indicate a physical fault with
