LegacyHive: Unpatched Windows Zero-Day Lets Standard Users Mount Another Account's Registry Hive
Researcher Nightmare Eclipse has dropped LegacyHive, a working PoC against the Windows User Profile Service that lets a standard user load another account's registry hive — no CVE, no patch, works on fully updated July 2026 systems.
RoguePlanet Gets a CVE: Microsoft Confirms Patch in Progress for Defender SYSTEM Race Condition (CVE-2026-50656)
One week after a public PoC dropped during Patch Tuesday, Microsoft has assigned CVE-2026-50656 to RoguePlanet — a Defender Malware Protection Engine race condition that hands SYSTEM on fully patched Windows 10 and 11 — and confirmed a fix is in flight. No patch yet.
DirtyDecrypt (CVE-2026-31635): Public PoC Roots Fedora, Arch, and openSUSE via the Kernel's RxGK Path
A released proof-of-concept weaponizes CVE-2026-31635, a missing copy-on-write guard in the Linux kernel's RxGK receive path, for local root on Fedora, Arch, and openSUSE Tumbleweed — and pod escape on affected worker nodes.
MiniPlasma: Public PoC Hands SYSTEM on Fully Patched Windows 11 via cldflt.sys

Dirty Frag chains an xfrm-ESP page-cache write (CVE-2026-43284) with an unpatched RxRPC page-cache write (CVE-2026-43500) for reliable root on most Linux distros. Embargo blew up early — public PoC is out, RxRPC fix is not.
