What an attacker can do

Local users can achieve a systemd-coredump deadlock by triggering a crash that has a long backtrace. NVD’s CVSS 3.1 assessment (base score 5.5/10) rates confidentiality and integrity impact as none; availability impact as high. Source advisory’s CVSS 3.1 assessment (base score 5.5/10) rates confidentiality and integrity impact as none; availability impact as high.
