Critical Windows Kernel Flaw Impacts All Versions, Patch Now!

CVSScvssV3_1: 8.8

Microsoft Windows is prone to a serious privilege escalation vulnerability, tracked as CVE-2024-21345, with a CVSS score of 8.8 out of 10. This means an attacker can exploit it to gain administrator access on affected systems.

The flaw exists in how the Windows kernel handles object permissions and privileges. A local attacker can leverage this to run arbitrary code with SYSTEM level access rights. This gives a hacker full control over a compromised computer.

All versions of Windows, including the latest Windows 11, are reported vulnerable. So desktops, laptops, servers and IoT devices running Windows could be at risk. Attackers may try to take advantage of this by pairing it with other exploits to infect systems with malware and move laterally within networks.

The best way to protect yourself is to install the latest security patch from Microsoft as soon as it is available. Make sure to keep Windows, as well as web browsers and other applications, updated with the latest patches. Using an antivirus program and practicing safe browsing habits can also help reduce risks.

Until a patch is available, limiting administrator accounts and applying the principle of least privilege can help minimize damage from successful exploitation of this critical vulnerability. Stay vigilant and stay safe!
