  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: iscsi_tcp: Check that sock is valid before iscsi_set_param()\n\nThe validity of sock should be checked before assignment to avoid incorrect\nvalues. Commit 57569c37f0ad (\"scsi: iscsi: iscsi_tcp: Fix null-ptr-deref\nwhile calling getpeername()\") introduced this change which may lead to\ninconsistent values of tcp_sw_conn->sendpage and conn->datadgst_en.\n\nFix the issue by moving the position of the assignment.",
