The vulnerability exists when the Driver Execution Environment (DXE) is active after a successful Power On Self Test (POST) in the UEFI firmware (also known as the BIOS). ). The UEFI's boot logo is replaced with the exploit payload at this point, and the exploit can then take control of the sys
In 2022, security researchers discovered a vulnerability in the Advanced Programmable Interrupt Controller (APIC) that allows for an attacker with root/admin privileges to gain access to encryption keys via the APIC by inspecting data transfers from L1 and L2 cache. [40] This vulnerability is the first architectural attack discovered on x86 CPUs.
Logo. The Common Vulnerabilities and Exposures (CVE) system provides a reference method for publicly known information-security vulnerabilities and exposures. [1] The United States' National Cybersecurity FFRDC, operated by The MITRE Corporation, maintains the system, with funding from the US National Cyber Security Division of the US Department of Homeland Security.

AMD Platform Security Processor settings in an UEFI configuration screen. The AMD Platform Security Processor (PSP), officially known as AMD Secure Technology, is a trusted execution environment subsystem incorporated since about 2013 into AMD microprocessors. [1]
The slab bootloader used by Windows RT could be unlocked using a vulnerability, but was silently patched by Microsoft in 2016. [31] UEFI Secure Boot on x86 systems can generally be unlocked. Apple
UEFI applications can be developed and installed independently of the original equipment manufacturers (OEMs). A type of UEFI application is an OS boot loader such as GRUB, rEFInd, Gummiboot, and Windows Boot Manager, which loads some OS files into memory and executes them. Also, an OS boot loader can provide a user interface to allow the ...
Rowhammer (also written as row hammer or RowHammer) is a computer security exploit that takes advantage of an unintended and undesirable side effect in dynamic random-access memory (DRAM) in which memory cells interact electrically between themselves by leaking their charges, possibly changing the contents of nearby memory rows that were not addressed in the original memory access.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
