CVE-2024-26760 Information

Description

scsi: target: pscsi: Fix bio_put() for error case

As of commit 066ff571011d (lock: turn bio_kmalloc into a simple kmalloc wrapper) a bio allocated by bio_kmalloc() must be freed by bio_uninit() and kfree(). That is not done properly for the error case hitting WARN and NULL pointer dereference in bio_free().
