CVE-2022-2526

9.8 criticalEPSS 1.3%

Critical (9.8). EPSS 1.3% chance of exploitation in the next 30 days.

A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later.
