Linux — Vulnerabilities & Security Advisories 17853

All 17853 CVE vulnerabilities found in Linux, with AI-generated Chinese analysis, references, and POCs.

This page documents Common Weakness Enumeration (CWE) vulnerabilities affecting the Linux operating system product. It aggregates security data related to weaknesses within the kernel, distributions, and associated utilities provided by various Linux vendors and maintainers. The collection encompasses a wide range of vulnerability types, including memory corruption issues, privilege escalation flaws, information leaks, and denial-of-service conditions. The database covers historical records spanning several decades, reflecting the evolution of the Linux ecosystem from its early releases to modern stable and development branches. This extensive time range allows for the analysis of long-term security trends and the remediation status of legacy systems that remain in production environments. Visitors to this resource can track vendor-specific advisories to stay informed about patches and updates released by major Linux distribution maintainers. You can also use the page to understand the characteristics and impact of specific weakness classes as they manifest in the Linux environment. Additionally, the interface supports looking up a specific product’s vulnerability history, enabling security professionals to assess risk exposure and prioritize mitigation efforts for critical infrastructure components. The data is organized to facilitate efficient searching and correlation between weakness identifiers and affected software versions, ensuring that administrators and developers have access to comprehensive security insights necessary for maintaining system integrity and compliance.
