Linux Kernel ksmbd Use-After-Free Remote Code Execution Vulnerability

[Jcenos7]

Hi,
Is CentOS 7 affected by this

Vulnerability:
Linux Kernel ksmbd Use-After-Free Remote Code Execution Vulnerability

CVEs:
ZDI-22-1690, ZDI-CAN-17816

Vulnerability Description:
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability, but only systems with ksmbd enabled are vulnerable.

The specific flaw exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the kernel.

I don't think CentOS 7 is affected because it only affects certain versions of version 5 of the Kernel.

Thank you whoever for your response!

Are ZDI-22-1690, ZDI-CAN-17816 same as CVE-2022-47939?
The latter https://access.redhat.com/security/cve/cve-2022-47939
does not affect any RHEL kernel.
