# CVE-2023-53464

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

scsi: iscsi_tcp: Check that sock is valid before iscsi_set_param()

The validity of sock should be checked before assignment to avoid incorrect
values. Commit 57569c37f0ad ("scsi: iscsi: iscsi_tcp: Fix null-ptr-deref
while calling getpeername()") introduced this change which may lead to
inconsistent values of tcp_sw_conn->sendpage and conn->datadgst_en.

Fix the issue by moving the position of the assignment.

## Patch verfügbar (OSV)

- Kernel ≥ 5.10.178
- Kernel ≥ 5.15.107
