## Overview

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

scsi: target: core: Fix null-ptr-deref in target_alloc_device()

There is a null-ptr-deref issue reported by KASAN:

BUG: KASAN: null-ptr-deref in target_alloc_device+0xbc4/0xbe0 [target_core_mod]
...
 kasan_report+0xb9/0xf0
 target_alloc_device+0xbc4/0xbe0 [target_core_mod]
 core_dev_setup_virtual_lun0+0xef/0x1f0 [target_core_mod]
 target_core_init_configfs+0x205/0x420 [target_core_mod]
 do_one_initcall+0xdd/0x4e0
...
 entry_SYSCALL_64_after_hwframe+0x76/0x7e

In target_alloc_device(), if allocing memory for dev queues fails, then
dev will be freed by dev->transport->free_device(), but dev->transport
is not initialized at that time, which will lead to a null pointer
reference problem.

Fixing this bug by freeing dev with hba->backend->ops->free_device().

## Affected

- `linux_kernel >= 5.11, < 5.15.170`
- `linux_kernel >= 5.16, < 6.1.115`
- `linux_kernel >= 6.2, < 6.6.59`
- `linux_kernel >= 6.7, < 6.11.6`
- `linux_kernel = 5.10.180`
- `linux_kernel = 6.12`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.11.6`
