NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable.
