NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd-boot-unsigned package and not the systemd-boot-unsigned package as distributed by RHEL.

A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages.
