## Overview

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: tipd: Remove WARN_ON in tps6598x_block_read

Calling tps6598x_block_read with a higher than allowed len can be
handled by just returning an error. There's no need to crash systems
with panic-on-warn enabled.

## Affected

- `linux_kernel < 4.19.218`
- `linux_kernel >= 4.20, < 5.4.162`
- `linux_kernel >= 5.5, < 5.10.82`
- `linux_kernel >= 5.11, < 5.15.5`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.15.5`
