Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: pscsi: Fix bio_put() for error case
As of commit 066ff571011d ("block: 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().
