Microsoft has released a massive set of 126 flaws affecting its software products, including one vulnerability that has been actively exploited in the wild. This latest update highlights the importance of staying vigilant with software security and emphasizes the need for organizations to prioritize patching and stay informed about the latest vulnerabilities.
Microsoft has released a massive set of security fixes to address 126 flaws affecting its software products. 11 vulnerabilities are rated as Critical, 112 as Important, and 2 as Low in severity. A critical elevation of privilege (EoP) flaw impacting the Windows Common Log File System (CLFS) Driver has been confirmed to be actively exploited in the wild. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added the vulnerability to the Known Exploited Vulnerabilities (KEV) catalog, requiring federal agencies to apply the fix by April 29, 2025.
Microsoft has released a massive set of security fixes to address a whopping 126 flaws affecting its software products, including one vulnerability that it said has been actively exploited in the wild. This latest update is a stark reminder of the importance of staying vigilant and up-to-date with the latest security patches.
The severity of these vulnerabilities can be gauged from the sheer number of criticality ratings assigned to them. Out of the 126 vulnerabilities, a whopping 11 are rated as Critical, 112 are rated as Important, and two are rated as Low in severity. Moreover, 49 of these vulnerabilities are classified as privilege escalation, 34 as remote code execution, 16 as information disclosure, and 14 as denial-of-service (DoS) bugs.
One of the most concerning vulnerabilities is an elevation of privilege (EoP) flaw impacting the Windows Common Log File System (CLFS) Driver (CVE-2025-29824, CVSS score: 7.8). This vulnerability stems from a use-after-free scenario, allowing an authorized attacker to elevate privileges locally. What makes this vulnerability particularly concerning is that Microsoft has confirmed active exploitation in the wild, yet at this time, no patch has been released for Windows 10 32-bit or 64-bit systems.
This lack of patch leaves a critical gap in defense for a wide portion of the Windows ecosystem. The development has prompted the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to add it to the Known Exploited Vulnerabilities (KEV) catalog, requiring federal agencies to apply the fix by April 29, 2025.
The active exploitation of this flaw has been linked to ransomware attacks against a small number of targets. The attackers have managed to exploit the vulnerability to execute code at the highest privilege level in Windows, without needing administrative privileges. This is a stark reminder that even local access can be sufficient for an attacker to gain significant control over a system.
In addition to this critical EoP vulnerability, Microsoft has also patched several other notable vulnerabilities this month. These include a security feature bypass flaw affecting Windows Kerberos (CVE-2025-29809), as well as remote code execution flaws in Windows Remote Desktop Services (CVE-2025-27480, CVE-2025-27482) and Windows Lightweight Directory Access Protocol (CVE-2025-26663, CVE-2025-26670).
Furthermore, multiple Critical-severity remote code execution flaws have been patched in Microsoft Office and Excel (CVE-2025-29791, CVE-2025-27749, CVE-2025-27748, CVE-2025-27745, and CVE-2025-27752). These vulnerabilities could be exploited by a bad actor using a specially crafted Excel document, resulting in full system control.
Capping off the list of critical flaws are two remote code execution vulnerabilities impacting Windows TCP/IP (CVE-2025-26686) and Windows Hyper-V (CVE-2025-27491) that could allow an attacker to execute code over a network under certain conditions.
In addition to Microsoft's latest security fixes, other vendors have also released updates to address several vulnerabilities in recent weeks. These updates are essential for ensuring the security of software systems and preventing potential attacks.
The sheer scale of these vulnerabilities serves as a stark reminder of the importance of regular patching and the need for organizations to stay vigilant when it comes to software security. The consequences of neglecting these vulnerabilities can be devastating, resulting in significant data breaches, ransomware attacks, and even system compromise.
In conclusion, Microsoft's latest security fixes are a crucial step towards mitigating the risks associated with elevation of privilege vulnerabilities. As we move forward, it is essential for organizations to prioritize software patching and stay informed about the latest vulnerabilities and security updates.
