Plus ModuleJail, a radical proposal for minimizing the impact of similar bugs

Another Linux kernel flaw has handed local unprivileged users a way to peek at files they should never be able to read, including root-only secrets such as SSH keys. The bug affects multiple LTS kernel lines from 5.10 upward, although a fix has already landed – and there is now a proposal for reducing the odds of similar surprises in future.

What FOSS analytics vendor Metabase memorably dubbed the strip-mining era of open source security continues. This time, the culprit is CVE-2026-46333, a local kernel vulnerability that lets an unprivileged user read files they should not be able to access, including those normally available only to root. An attacker who already has login access to an affected machine could therefore potentially grab SSH keys, password files, or other confidential credentials, as the KnightLiblog explains.
