Red Hat — Vulnerabilities & Security Advisories 787

Browse all 787 CVE security advisories affecting Red Hat. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Red Hat operates primarily as a provider of open-source enterprise software solutions, most notably its Linux operating system and container platforms. With 688 recorded Common Vulnerabilities and Exposures, the organization’s historical attack surface frequently involves remote code execution, cross-site scripting, and privilege escalation flaws within its middleware and management tools. These vulnerabilities often stem from complex codebases and third-party dependencies integrated into its distribution. Security characteristics are defined by a rigorous patching lifecycle and the Red Hat Security Response Team, which issues timely advisories for critical issues. While major public breaches directly attributed to Red Hat core infrastructure are rare, individual component flaws have occasionally allowed attackers to gain unauthorized access or execute arbitrary commands. The company maintains a strong reputation for transparency, providing detailed technical guidance to help administrators mitigate risks associated with its widely deployed enterprise technologies.
