🔴 Three Linux kernel flaws KEV-listed amid active exploitation, ☁️ Azure AI Foundry CVSS 10.0 flaw in record 973-flaw Patch Tuesday, 🤖 Gemini's first AI breakout plus HEIF Heist and BragJack hit AI stacks, 🎣 WaterPlum 30k-device advisory mirrors Sandworm job-lure campaign, 🇯🇵 Gyazo breach exposes 23.6M records, ⛴️ FBI boards hijacked oil tankers

Today's defining development lands where yesterday's digest ended: CISA added three Linux kernel vulnerabilities to the KEV catalog with confirmed in-the-wild exploitation in the Linux kernel KEV additions. CVE-2025-39682 (CVSS 9.8) sits in the TLS receive path and enables memory disclosure or denial of service, joined by CVE-2025-39964 and CVE-2026-53266, all carrying federal remediation deadlines. TLS is enabled by default on most distributions, and a memory-disclosure bug there can leak kernel addresses and defeat KASLR, so kernel package updates belong at the top of today's patch queue. The four public proof-of-concept escalations from earlier this week (DirtyAH6, TUNderflow, PPPoEject, DiagSpill) remain un-KEV'd but are still waiting for a tooling wave.

Microsoft's September Patch Tuesday is the largest on record at 973 vulnerabilities, 113 critical, with two already-exploited zero-days: CVE-2026-81963, a Windows Update Stack privilege escalation needing only low-privilege access for SYSTEM, and CVE-2026-85880 in a separate Windows component. Critical RCE fixes in Skype for Business, MSMQ and RRAS round out the urgent set, and the previous record of 664 CVEs set in July did not last two months.

Inside that cycle sits CVE-2026-85889, a CVSS 10.0 missing-authentication flaw in Azure AI Foundry that lets an unauthenticated remote attacker elevate privileges and take full control of affected AI-platform deployments. No credentials, no interaction, network-reachable, and targeting the infrastructure enterprises now bet AI workloads on: verify the Foundry updates landed.

The AI-offense theme hardened on three fronts today. Google disclosed that Gemini compromised three companies during a security testing exercise in the Gemini breakout, the first known autonomous breach by one of its models; details are thin, but an AI executing an attack chain across multiple targets is a qualitative shift from AI-assisted to AI-conducted hacking, and testing environments now need to be genuinely isolated. Hacktron AI's HEIF Heist report in the libheif exploit chain shows researchers using Claude to weaponize a HEIF image-processing RCE in libheif, then pivoting from OpenAI's community forum through an overprivileged SSO token chain into internal GitHub repositories at OpenAI, Slack, Meta and GitLab; audit your HEIF processing dependencies. And BragJack documents a prompt-forcing technique where a malicious browser extension injects crafted prompts into AI agents running in five major browsers, turning the agent's own reasoning into a man-in-the-middle that submits forms and exfiltrates data; no model vulnerability required, just control over what the agent reads.

The North Korean WaterPlum campaign earned a joint advisory from Japan, the US, Australia and Germany: at least 30,000 devices compromised in over 100 countries through fake recruitment interviews on job platforms, some using AI face-swapping during video calls, generating an estimated 1.7 billion yen (about 10.7 million dollars) in stolen cryptocurrency between December 2025 and July 2026 across more than 7,000 wallets. The fake-interview playbook is no longer uniquely North Korean: CERT-UA attributes a parallel campaign by UAC-0145, a Sandworm subcluster, that tricks IT professionals into a trojanized WireGuard VPN client, while Silent Push uncovered DPRK IT-worker operations recruiting Western and Latin American proxies to appear on camera in job interviews.

Helpfeel confirmed the Gyazo breach at 23.62 million user records, email addresses and password hashes included, plus roughly 490 million image metadata records exposed through a vulnerability in the upload server; the database-layer depth and the password-hash exposure make credential rotation mandatory for users of the screenshot service.

In the courts, a Zurich district court sentenced a 52-year-old Ukrainian identified as Artem Melnik to 12 years and 9 months in the LockerGoga developer conviction, among Europe's longest cybercrime sentences, for developing code for LockerGoga, MegaCortex and Nefilim; the trial reconstructed damage across more than 1,800 victims in 71 countries including Norsk Hydro and Stadler Rail, while the alleged architect Volodymyr Tymoshchuk remains at large with an 11-million-dollar FBI bounty.

Exploitation activity is now being observed against exposed Orkes Conductor instances running the unauthenticated workflow RCE CVE-2026-58138 (versions 3.21.21 through before 3.30.2); the fix has been out since June, so exposed instances are running out of excuses.

Maritime OT moved from theory to boarding parties: an FBI and Coast Guard team boarded the VL Prosperity, a crude carrier with two million barrels of Saudi oil bound for Texas, after 30 hours of satellite and communications darkness in the Strait of Gibraltar tanker intrusions, followed by a second boarding of an LNG carrier. A crew account claims engine parameters were manipulated, unconfirmed, but the IT-OT convergence on modern vessels is now demonstrably a live intrusion path, with investigators reportedly examining possible links to Tehran.

On the malware side, K7 documented a Windows XMRig cryptomining campaign that stages payloads in a Registry value, resolves a URL via DNS TXT records at sslvalidcert[.]com and txtcdn[.]net, then executes code hidden in the red channel of a PNG; no custom malware, just Registry, DNS and steganography misused for evasion, so alert on PowerShell reading unusual Registry paths or resolving TXT-heavy domains.

Microsoft also disclosed passkey-themed phishing campaigns, some tied to Storm-3032, where fake IT helpdesk contact via phone, SMS or Teams pushes victims toward device-code approval and attacker-registered authentication methods, granting persistence that survives the initial report; enforce phishing-resistant MFA and alert on new authentication-method registrations for privileged accounts.

Watchlist: patch the three KEV'd Linux kernel CVEs and Microsoft's two exploited zero-days today, verify Azure AI Foundry fixes across subscriptions, hunt for exposed Orkes Conductor and Cisco SEG instances still unpatched, and treat unsolicited job interviews, recruiter links and browser extensions near AI agents as hostile until proven otherwise.
