Linux Kernel
An open-source operating system kernel created and long maintained by Linus Torvalds, serving as the core component of Linux distributions.
Timeline (last 90 days)
For users who compile the Linux kernel themselves, attention must be paid to inheriting the kernel configuration (.config), module signing (Secure Boot), and regenerating the initramfs, otherwise the system may fail to boot.
Since the end of the 3.x era, Linus Torvalds has advanced the major version number to 4.x, 5.x, and 6.x.
The Linux kernel's minor version number (such as the "3" in 7.3) indicates the number of feature iterations under that major version, rather than "incompatible changes" in the traditional semantic versioning sense.
The official channel for obtaining Linux kernel source code is kernel.org, which provides complete tarballs (such as linux-7.3.tar.xz) and incremental patches (patch-7.3.x).
The Linux kernel uses a three-part version number of "major.minor.patch".
HackerOne researcher Paulos Yibelo (pwn.ai) discovered defects in the Linux kernel network protocol stack in a standard sandbox environment, and by sending carefully crafted packets from within the microVM achieved three kinds of attacks: host memory disclosure, crash, and code execution.
Almost all major cloud vendors isolate customer workloads at the same layer of the Linux kernel, and any kernel defect is a shared infrastructure risk.
Linux kernel development follows a time-driven release model: each cycle begins with a merge window of approximately two weeks, after which it enters a 6–8 week RC phase that accepts only bug fixes.
