Hi all,

I have Red Hat Enterprise Linux Server release 7.9 (Maipo) installed and i want check if i am vulnerable to CVE-2021-33909.
Is there any way to check for sure if i need to make updates or install patches?

I found this: https://access.redhat.com/solutions/3628301

According to the second way running:

yum list --cve CVE-2021-33909 | grep kernel.x86_64

In the results i find my kernel...so according to this i am not vulnerable.

Is this way correct?

Is there any other way to check if i am vulnerable to this specific CVE, and if yes how should i proceed?

Thanks in advance.
