NVD Description
Note: Versions mentioned in the description apply only to the upstream nss-systemd package and not the nss-systemd package as distributed by SLES.
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.
