[9] [10] [11] The vulnerabilities were mitigated by a new partitioning system that improves process and privilege-level separation. [12] 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]
In June 2022, multiple MMIO Intel CPUs vulnerabilities related to execution in virtual environments were announced. [51] The following CVEs were designated: CVE-2022-21123, CVE-2022-21125, CVE-2022-21166. In July 2022, the Retbleed vulnerability was disclosed affecting Intel Core 6 to 8th generation CPUs and AMD Zen 1, 1+ and 2 generation CPUs ...
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.
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 ...
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 ...
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]
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.
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]
