kernel — Vulnerabilities & Security Advisories 422

All 422 CVE vulnerabilities found in kernel, with AI-generated Chinese analysis, references, and POCs.

This page is an aggregation of Common Weakness Enumerations (CWE) associated with the Linux Kernel product from the primary vendor. It systematically collects security vulnerabilities affecting the core operating system component, providing a centralized view of the weaknesses that have been identified, analyzed, and published within the community and official tracking systems. The scope of this aggregation covers historical vulnerability data ranging from the early public disclosures of kernel security flaws up to the most recently cataloged entries, ensuring a comprehensive timeline of security incidents. Readers can utilize this resource to track vendor advisories and patch releases for specific kernel versions, allowing administrators to assess exposure and remediation urgency. Additionally, the page facilitates a deeper understanding of specific weakness classes, such as buffer overflows, race conditions, or privilege escalation paths, by contextualizing them within the kernel’s codebase and execution environment. Users may also look up a product’s vulnerability history to analyze trends, identify recurring issues in subsystems like memory management or network drivers, and inform long-term security architecture decisions. By consolidating these disparate reports, the aggregation serves as a reference for security researchers, developers, and system administrators seeking to maintain the integrity and stability of Linux-based systems. This approach supports informed decision-making regarding patching schedules, defensive coding practices, and threat modeling efforts without requiring manual compilation of scattered data sources.
