I am running Red Hat Enterprise 8.2 with a libc version glibc-2.28-189.5.el8_6.x86_64 which has a bug : glibc causes deadlock.
It was fixed on glibc-2.28-206.el8
How do I upgrade only the libc version? and make sure it is compatible with this OS?
You can use dnf to upgrade it - dnf update -y glibc.
Full example from a container on my machine:
[root@0df679e04d17 /]# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.2 (Ootpa)
[root@0df679e04d17 /]# rpm -qa glibc
glibc-2.28-101.el8.x86_64
[root@50a1768b4fcf /]# dnf update glibc
