Company Profile
The Linux Kernel is the core component of the Linux operating system, an open-source monolithic kernel managed by Linus Torvalds and a global community of developers. It powers the vast majority of cloud infrastructure, embedded systems, Android devices, and supercomputers, making it a critical target for security research and vulnerability patching. Its security relevance stems from its widespread deployment and the need for constant updates to address CVEs and maintain system integrity.
