Cybersecurity expert Nabeel Ahmed has confirmed the existence of a previously discovered critical vulnerability in Windows 8.1 and Windows Server 2012 R2 that leads to the infamous Blue Screen of Death, which users usually see when their PC encounters some serious unexpected error. According to the security expert, the glitch's use is limited to causing a BSoD. IT news media SecurityLab.ru, quoting the Microsoft Updates website, reports that the glitch has already been fixed.
Information about the proof of concept vulnerability appeared almost a year ago on the cyber security forum SANS ISC, where its author claimed that it managed to trigger a PC into a BSoD using glitched packet sent via the Microsoft Server Message Block (SMBv3). According to him, not only were Windows 8.1 and Server 2012 R2 vulnerable, but even the newest Windows 10.
