- CWE-416
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.
Affected configurations
• systemd project systemd 240
• netapp active iq unified manager
• netapp h300s firmware
• netapp h500s firmware
• netapp h700s firmware
• netapp h410s firmware
