Mitigation: Install vendor security updates. Enhance email security with additional filtering layers and user awareness training.
7. CVE-2025-78901: Privilege Escalation in Linux Kernel
CVSS Score: 7.8 (High)
Affected Systems: Linux kernel versions 5.x - 6.x
Impact: Local privilege escalation to root
Local users can exploit this vulnerability to gain root privileges on affected Linux systems.
Mitigation: Update kernel to patched version. Implement least privilege principles and monitor for suspicious privilege escalation attempts.
8. CVE-2025-89012: Remote Code Execution in IoT Devices
CVSS Score: 9.4 (Critical)
Affected Systems: Popular IoT device firmware
Impact: Botnet recruitment and lateral movement
A critical vulnerability in IoT device firmware allows remote code execution, enabling attackers to conscript devices into botnets or use them for lateral movement.
Mitigation: Update firmware immediately. Isolate IoT devices on separate network segments. Disable unnecessary services.
9. CVE-2025-90123: Directory Traversal in Web Applications
CVSS Score: 8.2 (High)
Affected Systems: Various web application frameworks
Impact: Unauthorized file access and system compromise
Attackers can traverse directory structures to access sensitive files, potentially leading to system compromise.
Mitigation: Update affected frameworks. Implement input validation and sanitization. Use WAF rules to block directory traversal attempts.
10. CVE-2025-01234: Authentication Weakness in Mobile Banking Apps
CVSS Score: 8.1 (High)
Affected Systems: Popular mobile banking applications
Impact: Account takeover and financial fraud
Weaknesses in authentication mechanisms allow attackers to compromise user accounts and conduct unauthorized transactions.
Mitigation: Update mobile apps to latest versions. Enable additional security features like biometric authentication and transaction alerts.
