Summary
systemd regression
Details

USN-5583-1 fixed vulnerabilities in systemd. Unfortunately this caused a regression by introducing networking problems for some users. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that systemd incorrectly handled certain DNS requests, which leads to user-after-free vulnerability. An attacker could possibly use this issue to cause a crash or execute arbitrary code. (CVE-2022-2526)
