polkit is a toolkit for managing policies relating to unprivileged processes communicating with privileged processes.
polkit has a race condition which potentially allows a process to change its UID/EUID via suid or pkexec before authentication is completed.
A local attacker could start a suid or pkexec process through a polkit-enabled application, which could result in privilege escalation or bypass of polkit restrictions.
There is no known workaround at this time.
