Microsoft's June 2026 Patch Tuesday set a record: ~200 CVEs, the biggest list ever.
We diffed ~130 of the patched binaries. Even at 200 CVEs, the advisories don't describe everything that changed.
Here's what the diffs show that the CVE text doesn't ๐งต

The slickest catch: one feature flag rerouted Kerberos PAC decoding to a new path across THREE binaries - LSASS, Credential Guard (LsaIso), the Kerberos client lib.
Kerberos & LSASS did get CVEs this month. The advisories just don't show this cross-binary shape.

The lesson: a record ~200 CVEs still isn't the whole picture. The binary diffs carry hardening the advisories never spell out.
We read them so you don't have to.

These are mainline -rc fixes: Cc: stable, no CVE yet by design. CVEs land later, on backport.
We read the merge graph so you see them now, not after the feed catches up.

Linux mainline quietly shipped a fix for a remote kernel heap overflow in the iSCSI target. It fires during login, before the CHAP password is ever checked.
No CVE. The commit just says "validate CHAP_R length before base64 decode."
Only watch CVE feeds? You missed it. ๐งต

7-Zip 26.01's changelog lists exactly ONE security fix.
We diffed the source, 26.00 -> 26.01. It silently shipped 14 MORE.
"Some bugs were fixed" was doing a lot of heavy lifting. ๐งต

Silent Patch Watch
Vendors often ship real security fixes as "minor bug fixes" โ no CVE, no advisory.
Every Thursday we diff a release and show the one that actually mattered, so you can update before attackers notice.
Follow ๐ for the first issue this week.
