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. [2]
The Common Attack Pattern Enumeration and Classification or CAPEC is a catalog of known cyber security attack patterns [1] to be used by cyber security professionals to prevent attacks.
The primary purpose of CVE, run by MITRE, is to attempt to aggregate public vulnerabilities and give them a standardized format unique identifier. [3] Many vulnerability databases develop the received intelligence from CVE and investigate further providing vulnerability risk scores, impact ratings, and the requisite workaround.
To address some of these criticisms, development of CVSS version 3 was started in 2012. The final specification was named CVSSv3.0 and released in June 2015. In addition to a Specification Document, a User Guide and Examples document were also released. [12] Several metrics were changed, added, and removed.
Common Weakness Enumeration (CWE) logo. The Common Weakness Enumeration (CWE) is a category system for hardware and software weaknesses and vulnerabilities.It is sustained by a community project with the goals of understanding flaws in software and hardware and creating automated tools that can be used to identify, fix, and prevent those flaws.

The Xen hypervisor project released patches to mitigate the vulnerability but they are not enabled by default. [73] Also in March 2024, a vulnerability in Intel Atom processors called Register File Data Sampling (RFDS) was revealed. [74] It was assigned CVE-2023-28746. Its mitigations incur a slight performance degradation. [75]
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 ...
Speculative execution exploit Variant 4, [8] is referred to as Speculative Store Bypass (SSB), [1] [9] and has been assigned CVE-2018-3639. [7] SSB is named Variant 4, but it is the fifth variant in the Spectre-Meltdown class of vulnerabilities. [7] Steps involved in exploit: [1] "Slowly" store a value at a memory location
