    On March 15, 2018, Intel reported that it will redesign its CPUs (performance losses to be determined) to protect against the Spectre security vulnerability, and expects to release the newly redesigned processors later in 2018. [22] [23] On May 3, 2018, eight additional Spectre-class flaws were reported.

  4. Speculative Store Bypass - Wikipedia

    en.wikipedia.org/wiki/Speculative_Store_Bypass

    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]

  5. Meltdown (security vulnerability) - Wikipedia

    en.wikipedia.org/wiki/Meltdown_(security...

    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 ...

  9. Lazy FP state restore - Wikipedia

    en.wikipedia.org/wiki/Lazy_FP_state_restore

    Lazy FPU state leak (CVE-2018-3665), also referred to as Lazy FP State Restore [1] or LazyFP, [2] [3] is a security vulnerability affecting Intel Core CPUs. [1] [4] The vulnerability is caused by a combination of flaws in the speculative execution technology present within the affected CPUs [1] and how certain operating systems handle context switching on the floating point unit (FPU).
