A use-after-free flaw was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in the SCSI sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information.

Mitigation

This flaw can be mitigated by preventing the affected iscsi_tcp.ko kernel module from loading during the boot time, ensure the module is added into the blacklist file.
