linux kernel hardening

About this tag
The linux kernel hardening tag on WindowsForum.com covers vulnerabilities and fixes that strengthen the Linux kernel against exploits, with a focus on USB security, denial-of-service prevention, and mandatory access control systems like AppArmor. Recent discussions include CVE-2026-31615, a Renesas USB gadget driver flaw where improper endpoint validation could be exploited, and CVE-2026-23404, an AppArmor kernel fix that prevents stack exhaustion during recursive profile removal. These topics are relevant to Windows users due to the growing integration of Linux workloads via WSL, Azure, and IoT devices, making kernel hardening a shared concern across mixed environments.
