Malicious microcode vulnerability discovered, fixes rolling out for Epycs at least Googlers have not only figured out how to break AMD's security – allowing them to load unofficial microcode into...
A team of security researchers has disclosed new side-channel vulnerabilities in modern Apple processors that could steal sensitive information from web browsers. [...]
The latest generations of Intel processors, including Xeon chips, and AMD's older Zen 1, Zen 1+, and Zen 2 microarchitectures on Linux are vulnerable to new speculative execution attacks that...
A team of researchers from the CISPA Helmholtz Center for Information Security in Germany has disclosed an architectural bug impacting Chinese chip company T-Head's XuanTie C910 and C920 RISC-V...
The bug allows malicious software and rogue privileged users with access to the operating system kernel to run code in System Management Mode, a highly privileged execution environment present in x86 processors from Intel and AMD. SinkClose is unique to AMD. SMM sits below the kernel and hypervisor, as well as applications, in that the management mode has unrestricted access to and control of the machine.

AMD's latest desktop CPUs feature lower prices yet again as Intel readies a fightback.
Intel has divulged more details on its Raptor Lake family of 13th and 14th Gen Core processor failures and the 0x129 microcode that's supposed to prevent further damage from occurring. The chipmaker previously disclosed that the so-called instability issue plaguing many Raptor Lake chips stems from an elevated operating voltage set by the processor itself.
Black Hat Computer security researchers at the CISPA Helmholtz Center for Information Security in Germany have found serious security flaws in some of Alibaba subsidiary T-Head Semiconductor's RISC-V processors. Thus the security issues here with the C910 lie with T-Head's own implementation of the ISA, specifically its non-standard implementation of the vector extension, and not the specs themselves nor other RISC-V chips.
Modern CPUs from Intel, including Raptor Lake and Alder Lake, have been found vulnerable to a new side-channel attack that could be exploited to leak sensitive information from the processors. The...
Modern Intel processors, including chips from the Raptor Lake and the Alder Lake generations are susceptible to a new type of a high-precision Branch Target Injection attack dubbed 'Indirector,' which could be used to steal sensitive information from the CPU. Indirector exploits flaws in Indirect Branch Predictor and Branch Target Buffer, two hardware components found in modern Intel CPUs, to manipulate speculative execution for data extraction. The Indirect Branch Predictor is designed to predict the target addresses of indirect branches using historical execution information, while the Branch Target Buffer predicts the target addresses of direct branches using a set-associative cache structure.
