A vulnerability found in the Linux kernel, specifically a flaw with the pseudo tty (pty) device, allows an unprivileged user to cause a denial of service (system crash) or potentially gain administrator privileges. A small number of CentOS and Ubuntu versions are vulnerable, thus we want to highlight the following information:
