How to fix?

There is no fixed version for RHEL:9 kernel-64k.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k package and not the kernel-64k package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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

scsi: iscsi_tcp: Fix UAF during login when accessing the shost ipaddress

If during iscsi_sw_tcp_session_create() iscsi_tcp_r2tpool_alloc() fails, userspace could be accessing the host's ipaddress attr. If we then free the session via iscsi_session_teardown() while userspace is still accessing the session we will hit a use after free bug.

Set the tcp_sw_host->session after we have completed session creation and can no longer fail.
