·
Updated

A use-after-free vulnerability was found in iscsiswtcpsessioncreate in drivers/scsi/iscsitcp.c in SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.

Other sources

Linux Kernel could allow a local attacker to obtain sensitive information, caused by a use-after-free flaw in the iscsiswtcpsessioncreate function in drivers/scsi/iscsitcp.c in the SCSI sub-component. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain kernel internal information, and use this information to launch further attacks against the affected system.
