Linux kernel flaw opens root-only files to unprivileged users
A recent flaw in the Linux kernel has allowed unprivileged users to access root-only files, including sensitive information like SSH keys. This vulnerability, identified as CVE-2026-46333, affects several long-term support kernel versions but has already been addressed with a fix. Additionally, a new security tool called ModuleJail has been proposed to help minimize the impact of similar vulnerabilities in the future.
- ▪The Linux kernel flaw allows local unprivileged users to read files they should not have access to.
- ▪The vulnerability affects multiple LTS kernel versions from 5.10 upward and has been fixed.
- ▪ModuleJail is a proposed tool that automates the process of blacklisting unused kernel modules to enhance security.
