Vulnerability Name:

CCN-242934

Published:2021-06-30
Updated:2021-06-30
Summary:Linux Kernel could allow a local attacker to obtain sensitive information, caused by a flaw with error handling of scsi_host_alloc() function. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain device name information, and use this information to launch further attacks against the affected system.
