systemd
use-after-free
resolved-dns-stream.
Security Advisory Description
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. (CVE-2022-2526)
Impact
There is no impact; F5 products are not affected by this vulnerability.
