CRITICAL ALERT: July 2025 Patch Tuesday Brings BitLocker Bypass & RDP Flaws

Описание: Get the essential breakdown of the July 2025 Microsoft Patch Tuesday updates in this deep dive analysis. We cut through the noise of 81 new CVEs to give system administrators and security professionals the actionable intelligence you need to prioritize patching and secure your systems. From critical Remote Code Execution (RCE) flaws in RDP and Microsoft Edge to alarming physical-access BitLocker bypasses, we cover the most significant threats this month.

This month's report, covering security updates released between July 2nd and July 8th, 2025, is substantial. We unpack the 80 Windows-based vulnerabilities and the one critical Chromium-based CVE affecting Microsoft Edge. Our analysis focuses heavily on the massive number of Elevation of Privilege (EOP) vulnerabilities, breaking down the common memory management flaws (use-after-free, heap overflows), race conditions, and logical errors plaguing core Windows components like the Graphics Component, NTFS, and various driver-level services.

We shine a spotlight on the most critical threats, including:

Remote Code Execution (RCE): Network-exploitable vulnerabilities in the Windows Connected Devices Platform, Miracast, and the RDP Client. Plus, a critical drive-by RCE in Microsoft Edge (CVE-2025-49713) that demands immediate attention.

Security Feature Bypass (SFB): A stunning cluster of vulnerabilities allowing an attacker with physical access to bypass BitLocker disk encryption, posing a major risk to laptops and mobile devices.

Information Disclosure: Potentially severe leaks from Windows Cryptographic Services and Hyper-V that can be exploited over the network.

Denial of Service & Spoofing: Disruptive threats to Hyper-V, Print Spooler, and SMB services.

We also discuss the OS-level mitigations required for new AMD processor hardware vulnerabilities. We conclude with the specific KB numbers for the main cumulative updates and emphasize the importance of defense-in-depth strategies beyond just patching.
