CVE-2026-59677 Details
Description
A Missing Authorization vulnerability in selinux policycoreutils seunshares allows a user that is running in unconfined context to kill e.g. root-owned processes running also in unconfined context This issue affects policycoreutils through 3.10.
A missing authorization vulnerability has been identified in the SELinux policycoreutils package, specifically in the 'seunshare' utility, which is part of the SELinux sandbox feature. This vulnerability allows unconfined users to terminate root-owned processes that are also running in an unconfined context. The issue arises because 'seunshare' is intended to be executed with elevated privileges, but the current SELinux policy does not properly confine its execution, leaving a gap that can be exploited to disrupt critical system processes.
The vulnerability has been fixed in the upstream release of the SELinux userspace utilities version 3.11. However, users on openSUSE Tumbleweed should ensure that 'seunshare' is installed with the setuid-root privileges, as this is not the default configuration.
