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 ...
In August 2021 a vulnerability called "Transient Execution of Non-canonical Accesses" affecting certain AMD CPUs was disclosed. [38] [39] [40] It requires the same mitigations as the MDS vulnerability affecting certain Intel CPUs. [41] It was assigned CVE-2020-12965. Since most x86 software is already patched against MDS and this vulnerability ...
Load value injection (LVI) is an attack on Intel microprocessors that can be used to attack Intel's Software Guard Extensions (SGX) technology. [1] It is a development of the previously known Meltdown security vulnerability. Unlike Meltdown, which can only read hidden data, LVI can inject data values, and is resistant to the countermeasures so ...
The Meltdown and Spectre CPU vulnerabilities hung like a shadow over the festivities of CES. What's typically a celebration of consumer electronics was instead a stark reminder of just how far ...
The post Intel chip vulnerability could give hackers access to sensitive information appeared first on The Block. Intel has disclosed a fault in its software chips that, if exploited, could allow ...

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".
In January 2018, the Meltdown vulnerability was published, known to affect Intel's x86 CPUs and ARM Cortex-A75. [22] [23] It was a far more severe vulnerability than the KASLR bypass that KAISER originally intended to fix: It was found that contents of kernel memory could also be leaked, not just the locations of memory mappings, as previously thought.
