Ventoy is a free and open-source utility used for creating bootable USB media storage devices with files such as .iso, .wim, .img, .vhd(x), and .efi.Once Ventoy is installed onto a USB drive, there is no need to reformat the disk to update it with new installation files; it is enough to copy the .iso, .wim, .img, .vhd(x), or .efi file(s) to the USB drive and boot from them directly.
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project.GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular ...
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 ...
In June 2021, two new vulnerabilities, Speculative Code Store Bypass (SCSB, CVE-2021-0086) and Floating Point Value Injection (FPVI, CVE-2021-0089), affecting all modern x86-64 CPUs both from Intel and AMD were discovered. [33]
Poor CPU cooling due to a CPU heatsink and case fans (or filters) that's clogged with dust or has come loose. Overclocking beyond the highest clock rate at which the CPU is still reliable. Failing motherboard. Failing processor. Failing memory. Failing I/O controllers, on either the motherboard or separate cards. Failing I/O devices.
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.
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU.. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.
In the x86 architecture, the CPUID instruction (identified by a CPUID opcode) is a processor supplementary instruction (its name derived from CPU Identification) allowing software to discover details of the processor.
