## Overview

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().

## Affected

- `linux_kernel >= 5.19, < 6.1.80`
- `linux_kernel >= 6.2, < 6.6.19`
- `linux_kernel >= 6.7, < 6.7.7`
- `linux_kernel = 6.8`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.7`
