Patch Tuesday Blues: Why August 2025 Feels Like Déjà Vu

The Never-Ending Cycle
Microsoft’s Patch Tuesday rolls around again, but the fixes feel familiar
Another month, another Patch Tuesday. Microsoft’s August 2025 update is live, and if you’re feeling a sense of déjà vu, you’re not alone. The company is rolling out fixes for 75 vulnerabilities—12 labeled 'critical'—but the real story isn’t the number. It’s the fact that we’re still patching the same types of flaws we’ve seen for years.
Remote code execution (RCE) bugs dominate the list, accounting for nearly half of the critical vulnerabilities. These aren’t exotic, edge-case exploits. They’re the kind of gaps that let attackers waltz into systems if left unpatched. And yet, here we are, still playing whack-a-mole with them in 2025.
The Usual Suspects
Windows, Office, and Azure—same players, same problems
Windows 11 and Server 2022 take the brunt of the patches, with 30 vulnerabilities addressed across the two. Office isn’t far behind, with a particularly nasty flaw (CVE-2025-32844) that could let malicious documents execute code just by being previewed in Outlook. Sound familiar? That’s because it’s a variation of a flaw patched in 2023.
Azure gets its share of attention too, with three critical fixes for its cloud services. One of them, CVE-2025-32851, could allow privilege escalation in multi-tenant environments—a nightmare scenario for shared hosting. Microsoft’s advisory is careful to note there’s 'no evidence of active exploitation,' but given how quickly cloud vulnerabilities get weaponized, that’s cold comfort.
The Elephant in the Room
Why are we still dealing with the same vulnerabilities?
Security experts aren’t surprised. 'We’re stuck in a loop,' says Tanya Janca, founder of We Hack Purple. 'Every Patch Tuesday, it’s RCEs, privilege escalations, and memory corruption. These aren’t new attack vectors. We know how to prevent them.'
The problem isn’t just technical—it’s cultural. Microsoft has made strides with its Secure Future Initiative, but legacy code and backward compatibility demands keep reintroducing old risks. Meanwhile, enterprises delay patches due to compatibility fears, creating windows of exposure that attackers exploit.
Case in point: One of this month’s critical bugs, CVE-2025-32847, affects a Windows component first introduced in 2012. Thirteen years later, it’s still causing headaches.
The Zero-Day Wildcard
Two vulnerabilities were already under attack before patches landed
This month’s update includes fixes for two zero-days—flaws attackers were actively exploiting before Microsoft could issue patches. One targets Windows Defender (CVE-2025-32849), ironically bypassing the very tool meant to stop such attacks.
Zero-days are the wildcards of Patch Tuesday. They’re rare, but when they appear, they’re often paired with sophisticated attacks. Mandiant’s threat intelligence team has already linked one of these to a known state-sponsored group, though they’re not naming names yet.
The takeaway? Patching can’t just be a monthly ritual. With zero-days in play, delays are gambling with security.
What’s Next?
The industry’s reckoning with 'patch fatigue'
IT teams are exhausted. A recent Ponemon study found that 68% of organizations skip some patches due to sheer volume. 'We’re reaching a breaking point,' says Chris Goettl at Ivanti. 'The model isn’t sustainable.'
Some are calling for radical shifts—smaller, more frequent updates or automated patching for critical systems. Others argue for rewriting legacy code, even if it breaks old applications. Neither solution is easy, but the status quo isn’t working.
As August’s patches roll out, one thing’s clear: Until we address the root causes, Patch Tuesday will keep feeling like groundhog day.
