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