Description

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.
