| CVE‑2023‑38046 (not listed but inferred from similar Chrome bugs) – omitted because no explicit CVE in supplied data. |
* “Actively exploited” means that threat‑intel reports, vendor advisories or public exploit code indicate real‑world use of the vulnerability.
Why these items are top‑priority
- Critical/high CVSS (≥ 7) and many at 9.3–9.8 – they give an attacker full control over the target system.
- Core libraries / platforms – Chrome/V8, Skia, Windows kernel components, OpenSSL‑like router firmware, Oracle IAM connector – all are widely deployed across enterprises and consumer devices.
- Authentication & encryption related flaws – e.g., Outlook Net‑NTLMv2 hash leak, Secure Boot bypass, remote code execution via web‑browser rendering engines (V8/Skia) directly affect credential confidentiality and integrity.
- IoT / router firmware – the MSI Radix AXE6600 series is a popular consumer/gaming router; each CVE gives remote attackers root on an internet‑exposed device, creating botnet or ransomware launch pads.
- Active exploitation – multiple entries are confirmed to be used by APT groups (e.g., APT37) or observed in the wild by security vendors, raising immediate risk.
Supply‑chain / open‑source relevance (Priority 2)
No explicit NPM/Maven/PyPI supply‑chain incidents were present in the supplied data for the requested period.
If such events appear later, they should be added under this heading with CVE IDs and affected packages.
Massive ransomware or state‑sponsored APT activity (Priority 3)
- APT37 leveraged CVE‑2022‑41128 (Outlook hash leak) in targeted attacks against South Korean organizations (late 2022).
- Large‑scale ransomware groups (Sovcali, Panzer, Qilin) are mentioned, but no technical details or CVEs were disclosed; therefore they fall outside the current high‑impact technical scope.
Quick remediation guidance (for SOC / DevSecOps)
| Vulnerability | Immediate mitigation |
|---|---|
| Chrome V8/Skia bugs (CVE‑2026‑3910, CVE‑2026‑3909) | Deploy latest Chrome stable channel; enforce CSP and X‑Content‑Type‑Options on web apps. |
| Oracle IAM Connector (CVE‑2026‑21992) | Apply Oracle security advisory patch; restrict network access to the connector endpoint. |
| MSI Radix AXE6600 firmware bugs (CVE‑2024‑7198x series) | Upgrade router firmware to version ≥ v781522 (or later); block external access to management ports; enable firewall rules limiting inbound traffic. |
| Windows kernel & driver flaws (CVE‑2023‑29336, CVE‑2023‑38178) | Apply latest cumulative updates for Windows 10/11 and Server 2019/2022; consider enabling Device Guard / Credential Guard. |
| Outlook Net‑NTLMv2 leak (CVE‑2022‑41128) | Disable NTLM where possible, enforce Kerberos; apply Microsoft’s mitigation script; monitor for unusual authentication traffic. |
| Secure Boot bypass (CVE‑2024‑38080) | Verify firmware signatures on boot media; consider enabling measured boot and TPM attestation. |
Bottom line:
The most critical threats in the period are the series of critical command‑injection bugs in MSI’s Radix AXE6600 router firmware, the Chrome/V8/Skia remote‑code‑execution flaws, the Oracle IAM connector RCE, and several high‑severity Windows kernel/driver vulnerabilities. All have public exploits or confirmed active use, so immediate patching, network segmentation, and monitoring are strongly recommended.
