CVE-2017-14489

Published: 15 September 2017

The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel through 4.13.2 allows local users to cause a denial of service (panic) by leveraging incorrect length validation.

From the Ubuntu Security Team

ChunYu Wang discovered that the iSCSI transport implementation in the Linux kernel did not properly validate data structures. A local attacker could use this to cause a denial of service (system crash).
