Transient execution CPU vulnerabilities are vulnerabilities in which instructions, most often optimized using speculative execution, are executed temporarily by a microprocessor, without committing their results due to a misprediction or error, resulting in leaking secret data to an unauthorized party.
The Problem Reports and Solutions Control Panel applet was replaced by the Maintenance section of the Action Center on Windows 7 and Server 2008 R2.. A new app, Problem Steps Recorder (PSR.exe), is available on all builds of Windows 7 and enables the collection of the actions performed by a user while encountering a crash so that testers and developers can reproduce the situation for analysis ...
In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations [1] in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code (i.e. unreachable memory). [2]
However, most general-purpose systems use only two rings, even if the hardware they run on provides more CPU modes than that. For example, Windows 7 and Windows Server 2008 (and their predecessors) use only two rings, with ring 0 corresponding to kernel mode and ring 3 to user mode, [7] because earlier versions of Windows NT ran on processors ...
Invalid data or code has been accessed An operation is not allowed in the current ring or CPU mode A program attempts to divide by zero (only for integers; with the IEEE floating point standard, this creates an infinity instead).
This undated photo released by the New York Police Department shows a suspect in the fatal shooting of UnitedHealthcare CEO Brian Thompson on Dec. 4, 2024, in a taxi.
Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. Some, however, must resort to exploits to run, because the manufacturer has attempted to lock the hardware to stop it from running unlicensed code. Most firmware hacks are free software.
Organizations that had not installed Microsoft's security update from March were affected by the attack. [40] Those still running unsupported versions of Microsoft Windows , such as Windows XP and Windows Server 2003 [ 41 ] [ 42 ] were at particularly high risk because no security patches had been released since April 2014 for Windows XP and ...
