On 8 October 2018, Intel is reported to have added hardware and firmware mitigations regarding Spectre and Meltdown vulnerabilities to its Coffee Lake-R processors and onwards. [ 13 ] On 18 October 2018, MIT researchers suggested a new mitigation approach, called DAWG (Dynamically Allocated Way Guard), which may promise better security without ...
On March 5, 2020, computer security experts reported another Intel chip security flaw, besides the Meltdown and Spectre flaws, with the systematic name CVE-2019-0090 (or "Intel CSME Bug"). [16] This newly found flaw is not fixable with a firmware update, and affects nearly "all Intel chips released in the past five years".
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 ...
The vulnerabilities were dubbed Spectre and Meltdown , and provided malicious actors with avenues to access sensitive data -- such as usernames and passwords -- even if stored in protected memory ...
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 ...
Speculative Store Bypass (SSB) (CVE-2018-3639) is the name given to a hardware security vulnerability and its exploitation that takes advantage of speculative execution in a similar way to the Meltdown and Spectre security vulnerabilities. [1] It affects the ARM, AMD and Intel families of processors.
Retbleed is a speculative execution attack on x86-64 and ARM processors, including some recent Intel and AMD chips. [1] [2] First made public in 2022, it is a variant of the Spectre vulnerability which exploits retpoline, which was a mitigation for speculative execution attacks.
This vulnerability is the first architectural attack discovered on x86 CPUs. This differs from Spectre and Meltdown which use a noisy side channel. This exploit currently affects Intel Core 10th, 11th and 12th generations, and Xeon Ice Lake microprocessors. [41] [42]
