CVE-2016-2568 2 Freedesktop, Redhat 2 Polkit, Enterprise Linux 2026-05-13 4.4 MEDIUM 7.8 HIGH
pkexec, when used with --user nonpriv, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer.
CVE-2026-4897 2 Freedesktop, Redhat 3 Polkit, Enterprise Linux, Openshift Container Platform 2026-04-21 N/A 5.5 MEDIUM
A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system.
