Linux kernel is vulnerable to denial of service. An unauthenticated remote attacker is able to crash the system due to a stack-based buffer overflow in the chap_server_compute_md5()
function in the ISCSI target code. Privilege escalation and unauthorized access to data exported by an iSCSI target is also possible upon successfully exploition of the vulnerability.
