Details

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.
