ZOMG! It's freakin Patch Tuesday again. And Microsoft has patched a staggering 167 security holes (think more people are using AI to find bugs, maybe?)
tl;dr: There's something for everyone today, like an Adobe Reader 0day that's apparently been exploited since at least November 2025; a SharePoint zero-day; and a fix for BlueHammer -- a Windows Defender bug for which there is working exploit code that no longer works if you install today's Windows updates (as per @wdormann).

Analysis Summary
Microsoft released 167 security patches on April 2026 Patch Tuesday, including an actively exploited SharePoint zero-day and an Adobe Reader zero-day that has been exploited since November 2025 according to Krebs. The patch volume is unusually large and may reflect AI-assisted bug discovery accelerating vulnerability findings. Notably, one BlueHammer Windows Defender bug now has a working exploit that's fixed by today's updates — organizations that haven't patched yet remain at risk from active exploitation.
Claims Analysis (4)
“Microsoft has patched 167 security holes”
Independent sources cite 167-168 vulnerabilities. Minor variance in exact count across sources (167 vs 168) is within normal reporting precision.
“Adobe Reader 0day has apparently been exploited since at least November 2025”
Web sources confirm zero-day patching but do not independently verify November 2025 exploitation timeline. Specific exploitation date unconfirmed.
“There is a SharePoint zero-day”
CyberScoop and BleepingComputer both confirm actively exploited SharePoint zero-day patched in April 2026 Patch Tuesday.
“BlueHammer is a Windows Defender bug with working exploit code”
BlueHammer bug mentioned but no independent source in search results explicitly confirms exploit code status or description as Windows Defender bug.
