RedSun (CVE-2026-41091) and UnDefend (CVE-2026-45498) are confirmed exploited and in CISA KEV. A patched Windows isn't enough: how to check your Defender engine 1.1.26040.8 / platform 4.18.26040.7.
CVE-2026-5426 zero-day: KnowledgeDeliver's shared ASP.NET machineKey → ViewState RCE → Godzilla in memory → Cobalt Strike via JS tampering. Hunting starts at Event ID 1316.
After Rift, two more nginx CVEs landed in late May 2026: njs js_fetch_proxy heap overflow CVE-2026-8711 and a second rewrite-module heap overflow CVE-2026-9256. Both pre-auth, CVSS v4.0 9.2, config-specific. Concrete grep checks and patch paths.
Walking through Dirty Pipe (CVE-2022-0847) from a 2026 angle: one uninitialized pipe_buffer.flags bit kept PIPE_BUF_FLAG_CAN_MERGE alive into splice'd pages, plus patched-kernel checks for distros and containers.
Microsoft assigned CVE-2026-45585 to YellowKey: strip autofstx.exe from WinRE BootExecute and move TPM-only BitLocker to TPM+PIN. No patch ETA; Chaotic Eclipse claims a TPM+PIN bypass PoC.
DirtyDecrypt PoC proves local root via Linux RxGK page cache writes on Fedora, Arch, and Tumbleweed with CONFIG_RXGK=y. NVD describes CVE-2026-31635 only as a DoS; Ubuntu LTS and Debian stable stock kernels are not affected. Check commands and container mitigation included.
Chaotic Eclipse's MiniPlasma takes SYSTEM on fully patched Windows 11 May 2026 by re-triggering CVE-2020-17103 in cldflt.sys, the same bug James Forshaw reported in 2020 and Microsoft supposedly fixed that December. Will Dormann confirmed the PoC works; the latest Insider Canary blocks it. No new CVE assigned yet, and the regression sits next to the actively exploited CVE-2025-62221 in the same driver.
Chaotic Eclipse released YellowKey and GreenPlasma PoCs one day after May 2026 Patch Tuesday. A USB-borne FsTx folder plus a Ctrl-key reboot drops cmd.exe inside WinRE on a BitLocker-protected machine. Covers WinRE-only behavior, the CTFMON SYSTEM elevation path, the RedSun silent-patch dispute, and what defenders can actually do while unpatched.
What to patch, rotate, and grep after OpenClaw 2026.4.22. Walks CVE-2026-44112/44113/44115/44118 as one chain on agent runtime, with detection log fields and 24h/1w response steps.
Composer 2.9.8/2.2.28 fix CVE-2026-45793: GitHub's new GITHUB_TOKEN includes hyphens that Composer's old regex rejects, leaking the token into CI logs as plaintext.
Fragnesia (CVE-2026-46300) overwrites the Linux page cache via XFRM ESP-in-TCP. The Dirty Frag workaround still applies, but IPsec hosts need to check side effects first.
137 CVEs, no zero-days. Netlogon and DNS Client RCEs (both CVSS 9.8) lead — compared against ZeroLogon/SIGRed, with patch priority tiers and detection notes for SOC teams.
