How to fix?

There is no fixed version for RHEL:8 openshift/ose-rhel-coreos-9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift/ose-rhel-coreos-9 package and not the openshift/ose-rhel-coreos-9 package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

nvmet-auth: zero the AUTH_RECEIVE response buffer

nvmet_execute_auth_receive() allocates the response buffer with kmalloc() sized by the host-supplied AUTH_RECEIVE allocation length, but the DH-HMAC-CHAP builders write only a fixed-size message into it. The full allocation length is then copied to the wire by nvmet_copy_to_sgl(), so a remote initiator receives the bytes past the built message -- up to nearly a page of uninitialized slab -- during the pre-authentication handshake.

Allocate the buffer with kzalloc() so the unwritten tail is zeroed before it is sent; conforming responses are unaffected.
