Including to the sense of urgency with this month’s patch batch from Redmond are fixes for 2 different weaknesses that now have public proof-of-concept exploits out there.
Microsoft and a number of other safety companies have disclosed that attackers are exploiting a pair of bugs within the Home windows Widespread Log File System (CLFS) driver that permit attackers to raise their privileges on a susceptible machine. The Home windows CLFS is a important Home windows element liable for logging companies, and is extensively utilized by Home windows system companies and third-party functions for logging.

Kev Breen, senior director of menace analysis at Immersive Labs, stated privilege escalation bugs assume an attacker already has preliminary entry to a compromised host, sometimes by way of a phishing assault or by utilizing stolen credentials. But when that entry already exists, Breen stated, attackers can achieve entry to the rather more highly effective Home windows SYSTEM account, which might disable safety tooling and even achieve area administration degree permissions utilizing credential harvesting instruments.
“The patch notes don’t present technical particulars on how that is being exploited, and no Indicators of Compromise (IOCs) are shared, that means the one mitigation safety groups have is to use these patches instantly,” he stated. “The typical time from public disclosure to exploitation at scale is lower than 5 days, with menace actors, ransomware teams, and associates fast to leverage these vulnerabilities.”
Two different zero-days patched by Microsoft at present additionally have been elevation of privilege flaws: CVE-2025-32709, which considerations afd.sys, the Home windows Ancillary Operate Driver that permits Home windows functions to hook up with the Web; and CVE-2025-30400, a weak point within the Desktop Window Supervisor (DWM) library for Home windows. As Adam Barnett at Rapid7 notes, tomorrow marks the one-year anniversary of CVE-2024-30051, a earlier zero-day elevation of privilege vulnerability on this similar DWM element.

Stated baggage contains new synthetic intelligence (AI) capabilities, together with the controversial Recall characteristic, which continuously takes screenshots of what customers are doing on Home windows CoPilot-enabled computer systems.
Microsoft went again to the drafting board on Recall after a fountain of unfavourable suggestions from safety specialists, who warned it might current a lovely goal and a possible gold mine for attackers. Microsoft seems to have made some efforts to forestall Recall from scooping up delicate monetary data, however privateness and safety considerations nonetheless linger. Former Microsoftie Kevin Beaumont has an excellent teardown on Microsoft’s updates to Recall.
In any case, windowslatest.com studies that Home windows 11 model 24H2 reveals up prepared for downloads, even when you don’t need it.
