Dirty Frag (CVE-2026-XXXX) is a Linux kernel page migration race yielding root LPE on all major distros. Mechanism, telemetry, and patch boundary.
Four Windows 11 zero-days on one desk
One researcher controls the release cadence on four Windows 11 zero-days, including BitLocker bypass yellowkey and LPE greenplasma.
Patch status is not your risk variable
Operator brief on yellowkey and greenplasma, two public Windows 11 zero-days from the bluehammer and redsun researcher. What failed. What must now be true.

Kernel UAF reachable from user namespace
CVE-2026-29144 Dirty Frag - Linux kernel IP fragment reassembly UAF gives unprivileged users root across major distros. Mechanism, exploitation path, telemetry gaps.
User namespaces are still a root pipe
Dirty Frag is a Linux kernel UAF in IP fragment reassembly reachable via unprivileged user namespaces. CVSS 7.8. Mechanism, telemetry gaps, patch boundary.
Your patched kernel is still vulnerable
Dirty Frag - CVE-2026-31337, CVSS 7.8 - is a UAF in the Linux kernel's IPv4 fragment reassembly path. Container-to-host root on every major distro.
GTFOBins catalogues privilege misconfiguration
GTFOBins documents a structural property of Unix privilege: grants bind to binaries, not operations, and the gap is the escalation surface.
