zephyrproject — Vulnerabilities & Security Advisories 80

Browse all 80 CVE security advisories affecting zephyrproject. AI-powered Chinese analysis, POCs, and references for each vulnerability.

This page documents Common Vulnerabilities and Exposures (CVEs) associated with the zephyrproject vendor in the context of open-source operating system weaknesses. It aggregates security issues affecting Zephyr, a real-time operating system (RTOS) designed for resource-constrained and connected IoT devices. The database collects vulnerability records spanning from the earliest disclosed issues in 2017 to the most recent updates in 2024. This comprehensive timeline captures the evolution of security risks within the Zephyr codebase as it matured and gained widespread adoption across various hardware platforms. The scope includes flaws related to buffer overflows, race conditions, improper access controls, and other common software defects identified by the Open Source Security Foundation (OpenSSF) and other security researchers. Users can utilize this resource to track vendor advisories issued by the Zephyr project maintainers, providing insight into how critical flaws are disclosed and patched over time. Additionally, the page serves as a reference for understanding specific weakness classes within real-time embedded environments, highlighting patterns in code quality and security practices. Visitors may also look up a product's vulnerability history to assess the security posture of systems relying on Zephyr RTOS. By reviewing these aggregated data points, developers and security analysts can better evaluate risk exposure and implement appropriate mitigation strategies for their IoT deployments.
