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".
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.
In 2017, two CPU vulnerabilities (dubbed Meltdown and Spectre) were discovered, which can use a cache-based side channel to allow an attacker to leak memory contents of other processes and the operating system itself. A timing attack watches data movement into and out of the CPU or memory on the hardware running the cryptosystem or algorithm ...
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 ...

💡 Expert tip: To save money on your consolidation loan, consider lenders like LightStream or Discover or PenFed that don't charge origination fees. Also, check if your lender offers rate ...
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]
A new federal report shows that one drink per day could raise the risk of liver damage and several cancers. The report follows a recommendation by the U.S. Surgeon General on safe alcohol ...
