CVE-2022-2526 (systemd) | allinfosecnews.com

Sept. 9, 2022, 3:15 p.m. |

National Vulnerability Database web.nvd.nist.gov

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.
