Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
A part of the Intel AMT web management interface, accessible even when the computer is sleeping. Intel Active Management Technology (AMT) is hardware and firmware for remote out-of-band management of select business computers, [1] [2] running on the Intel Management Engine, a microprocessor subsystem not exposed to the user, intended for monitoring, maintenance, updating, and repairing systems ...
Website. https://downfall.page/. Downfall, known as Gather Data Sampling ( GDS) by Intel, [ 1] is a computer security vulnerability found in 6th through 11th generations of consumer and 1st through 4th generations of Xeon Intel x86-64 microprocessors. [ 2] It is a transient execution CPU vulnerability which relies on speculative execution of ...
EternalBlue[ 5] is a computer exploit software developed by the U.S. National Security Agency (NSA). [ 6] It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network. The NSA knew about this vulnerability but did not disclose it to Microsoft for several years, since ...
The vulnerability is known to affect Skylake and later processors from Intel and Zen-based processors from AMD. [ 54] In February 2023, a team of researchers at North Carolina State University uncovered a new code execution vulnerability called Spectre-HD, also known as "Spectre SRV" or "Spectre v6".
Transient execution CPU vulnerabilities are vulnerabilities in a computer system in which a speculative execution optimization implemented in a microprocessor is exploited to leak secret data to an unauthorized party. The archetype is Spectre, and transient execution attacks like Spectre belong to the cache-attack category, one of several ...
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 ...
Foreshadow, known as L1 Terminal Fault ( L1TF) by Intel, [ 1][ 2] is a vulnerability that affects modern microprocessors that was first discovered by two independent teams of researchers in January 2018, but was first disclosed to the public on 14 August 2018. [ 18] The vulnerability is a speculative execution attack on Intel processors that ...
