The user will only see the blue screen if the system is not configured to automatically restart (which became the default setting in Windows XP SP2). Otherwise, it appears as though the system simply rebooted (though a blue screen may be visible briefly). In Windows, bug checks are only supported by the Windows NT kernel.
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 ...
SWAPGS, also known as Spectre variant 1, is a computer security vulnerability that utilizes the branch prediction used in modern microprocessors. [1] [2] [3] Most processors use a form of speculative execution, this feature allows the processors to make educated guesses about the instructions that will most likely need to be executed in the near future.
Robustness testing [5] (also known as syntax testing, fuzzing or fuzz testing) is a type of fault injection commonly used to test for vulnerabilities in communication interfaces such as protocols, command line parameters, or APIs. The propagation of a fault through to an observable failure follows a well-defined cycle.
In software development, time-of-check to time-of-use (TOCTOU, TOCTTOU or TOC/TOU) is a class of software bugs caused by a race condition involving the checking of the state of a part of a system (such as a security credential) and the use of the results of that check.
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.
However, because of the design of the Windows kernel, Kernel Patch Protection cannot completely prevent kernel patching. [ 2 ] [ 3 ] This has led to criticism that since KPP is an imperfect defense, the problems caused to antivirus vendors outweigh the benefits because authors of malicious software will simply find ways around its defenses.
Linux kernel developers chose not to add mitigations citing performance concerns. [72] The Xen hypervisor project released patches to mitigate the vulnerability but they are not enabled by default. [73] Also in March 2024, a vulnerability in Intel Atom processors called Register File Data Sampling (RFDS) was revealed. [74] It was assigned CVE ...
