CVE-2022-2526: resolved: pin stream while calling callbacks for it · systemd/systemd@d973d94

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.
