Intel Admits It Won't Be Possible to Fix Spectre (V2) Flaw in Some Processors
As speculated by the researcher who disclosed Meltdown and Spectre flaws in Intel processors, some of the Intel processors will not receive patches for the Spectre variant 2 side-channel analysis attack In a recent microcode revision guidance PDF, Intel admits that it would not be possible to...
Another Branch Prediction Attack
When Spectre and Meltdown were first announced earlier this year, pretty much everyone predicted that there would be many more attacks targeting branch prediction in microprocessors. Here's another one: In the new attack, an attacker primes the PHT and running branch instructions so that the PHT...
hw: cpu: speculative execution permission faults handling
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions a commonly used performance optimization. There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant...
Debian DSA-4120-1 : linux - security update (Meltdown) (Spectre)
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker...

Intel AMT Loophole Allows Hackers to Gain Control of Some PCs in Under a Minute
Researchers have found a loophole in Intel processors that allow an attacker to bypass logins and place backdoors on laptops, allowing adversaries remote access to laptops. Researchers at F-Secure, that first identified the attack strategy, say the loophole can be exploited in less than one minut...
Debian DSA-4082-1 : linux - security update (Meltdown)
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2017-5754 Multiple researchers have discovered a vulnerability in Intel processors, enabling an attacker controlling an unprivileged process to...
The vulnerability of Intel and ARM processors is caused by a memory access control error during speculative execution of processor instructions, allowing attackers to disclose protected information.
The vulnerabilities of Intel and ARM processors stem from errors in memory access control during speculative execution of processor instructions. Exploiting these vulnerabilities allows attackers to gain access to protected memory from a program that does not have the necessary privileges. This i...
The vulnerabilities of Intel, ARM, and AMD processors stem from the unique workings of the branch prediction module, which allows attackers to exploit the protected information.
The vulnerabilities of Intel, ARM, and AMD processors are related to the characteristics of the branch prediction module’s operation. Exploiting these vulnerabilities allows attackers to gain access to protected memory from a program that does not have the necessary privileges, by creating...
