CVE-2024-50153

Summary

CVE-2024-50153 is a vulnerability affecting the Linux kernel where a null-ptr-deref issue was identified in the 'target_alloc_device()' function of the 'scsi' driver. This issue occurs when memory allocation for dev queues fails, and 'dev' is freed before 'dev->transport' is initialized, leading to a null pointer reference problem. The vulnerability was discovered using the KASAN tool and could potentially result in system crashes or other unintended behavior. The issue has been resolved by freeing 'dev' using 'hba->backend->ops->free_device()' instead of 'dev->transport->free_device()'.
