A vulnerability in the Linux Kernel could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system. The vulnerability is due to improper processing of authentication requests by the chap_server_compute_md5() function, as defined in the drivers/target/iscsi_target_auth.c source code file of the affected software. An attacker could exploit this vulnerability by sending an authentication request from an Internet Small Computer System Interface (iSCSI) initiator to a targeted system that has iSCSI enabled. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-14633
