Comprehensive Threat Exposure Management Platform
Hive Pro recognized in Gartner® Magic Quadrant™ for Exposure Assessment Platform, 2025 Watch platform in action
In November 2025, the Linux ecosystem experienced a significant security patching cycle, with more than 1,384 new vulnerabilities discovered and addressed across major Linux distributions including Debian, Red Hat, OpenSUSE, and Ubuntu. During this period, over 2,692 vulnerabilities were highlighted with corresponding hotfixes and patches released. These Linux kernel vulnerabilities span information disclosure, privilege escalation, and code execution threats. HiveForce Labs identified 13 severe vulnerabilities that are actively exploited or have high exploitation potential, requiring immediate attention from security teams. Organizations running Linux systems must upgrade to the latest versions with necessary security patches and implement appropriate security controls to ensure protection against these critical Linux security flaws.
The November 2025 Linux patch cycle addressed thousands of security vulnerabilities across major distributions and related products. From this broader pool, HiveForce Labs identified 13 high-priority vulnerabilities that are already being exploited or are highly likely to be weaponized. These Linux kernel security weaknesses enable dangerous attack tactics including execution and privilege escalation.
Linux Kernel Vulnerabilities:
CVE-2024-50302 is a Linux Kernel Use of Uninitialized Resource Vulnerability originating from the HID subsystem, potentially leaking kernel memory. This zero-day vulnerability affects Linux Kernel, Red Hat Enterprise Linux CoreOS, Debian, Ubuntu, SUSE, Amazon Linux, and Oracle Linux. The attack vector is local with information disclosure impact.
CVE-2024-53104 is a Linux Kernel Out-of-Bounds Write Vulnerability in the UVC driver enabling physical privilege escalation. This zero-day affects Linux Kernel, Debian, Ubuntu, SUSE, ALT Linux, and Red Hat.
CVE-2024-53150 is a Linux Kernel Out-of-Bounds Read Vulnerability in the USB-audio driver that leaks sensitive data. This zero-day impacts Linux Kernel, Debian, Ubuntu, RedHat, SUSE, and Oracle Linux.
CVE-2024-53197 is a Linux Kernel Out-of-Bounds Access Vulnerability exploitable via malicious USB devices to manipulate memory, escalate privileges, or execute code. This zero-day affects Linux Kernel, Debian, Ubuntu, RedHat, SUSE, and Oracle Linux.
Browser and Application Vulnerabilities:
CVE-2025-13223 is a Google Chromium V8 Type Confusion Vulnerability allowing heap corruption, a common path to remote code execution. This zero-day affects Google Chrome versions prior to 142.0.7444.175.
CVE-2025-47151 is a Lasso SAML Library Type Confusion Vulnerability in Entr’ouvert Lasso versions 2.5.1 and 2.8.2, enabling arbitrary code execution and putting authentication architectures at risk. Affected platforms include Ubuntu, Suse, Amazon, Debian, Red Hat, and Oracle.
Web Application and Infrastructure Vulnerabilities:
CVE-2025-55754 is an Apache Tomcat Improper Neutralization Vulnerability involving improper handling of ANSI escape sequences in log messages, allowing attackers to manipulate console output or trick administrators into executing harmful commands.
CVE-2025-64459 is a Django SQL Injection Vulnerability in Django’s ORM layer due to unsafe handling of the _connector parameter, giving attackers ability to craft malicious SQL queries and compromise backend databases.
Container Security Vulnerabilities:
CVE-2025-40778 is a BIND 9 Cache Poisoning Vulnerability via unsolicited answer records affecting Ubuntu, Red Hat, Amazon, Suse, Debian, and Oracle.
CVE-2025-52565 is a runc Insufficient Validation Vulnerability causing denial of service.
CVE-2025-31133 is a runc maskedPaths Feature Bypass Vulnerability enabling information disclosure and denial of service.
CVE-2025-52881 is a runc Racing Container Vulnerability allowing container escape, denial of service, and privilege escalation.
CVE-2025-57108 is a Kitware VTK Heap Use-after-free Vulnerability enabling arbitrary code execution and memory corruption.
Prioritize Patch Management: Stay on top of Linux kernel security updates, especially for the Linux kernel, Django, Chromium, Tomcat, and SAML libraries. Applying patches quickly drastically reduces the attack surface and keeps known exploits from becoming real incidents.
Strengthen Endpoint and USB Security: Since several Linux kernel vulnerabilities involve USB drivers, restrict the use of untrusted USB devices. Enforce physical security rules, disable unused USB ports where possible, and use endpoint protection to flag suspicious device behavior.
Harden Authentication Systems: Flaws in SSO and SAML components highlight the importance of secure identity infrastructure. Regularly review SSO configurations, rotate secrets, and ensure that SAML libraries and dependencies are always up to date.
Improve Code and Dependency Hygiene: For teams managing web applications, treat third-party libraries as part of your threat surface. Track dependency updates, use automated scanners, and avoid outdated components in production environments.
Implement Least Privilege Everywhere: Make it harder for attackers to escalate privileges by limiting what each user, service, or process can access. Even a kernel or application flaw becomes less dangerous when permissions are tightly controlled.
Quickly Isolate and Contain the Impact: The moment you suspect exploitation—whether it’s a kernel privilege escalation, malicious USB activity, or suspicious SQL behaviour—immediately isolate the affected system. Disconnect it from the network, block risky processes, and stop any ongoing activity.
Investigate, Patch, and Restore Safely: After containment, begin a focused investigation to confirm how the vulnerability was exploited and what level of access the attacker achieved. Review system logs, check for privilege abuse, memory manipulation, or database tampering, and apply all missing patches for the Linux kernel, Django ORM, Tomcat, Chrome V8, or SAML libraries.
