In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Fix null-ptr-deref in targetallocdevice()
There is a null-ptr-deref issue reported by KASAN:
BUG: KASAN: null-ptr-deref in targetallocdevice+0xbc4/0xbe0 [targetcoremod] ... kasanreport+0xb9/0xf0 targetallocdevice+0xbc4/0xbe0 [targetcoremod] coredevsetupvirtuallun0+0xef/0x1f0 [targetcoremod] targetcoreinitconfigfs+0x205/0x420 [targetcoremod] dooneinitcall+0xdd/0x4e0 ... entrySYSCALL64afterhwframe+0x76/0x7e
In targetallocdevice(), 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().
