How to fix?

Upgrade Centos:9 glibc-langpack-tr to version 0:2.34-60.el9_2.7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-langpack-tr package and not the glibc-langpack-tr package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
