## Overview

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

ice: Fix improper extts handling

Extts events are disabled and enabled by the application ts2phc.
However, in case where the driver is removed when the application is
running, a specific extts event remains enabled and can cause a kernel
crash.
As a side effect, when the driver is reloaded and application is started
again, remaining extts event for the channel from a previous run will
keep firing and the message "extts on unexpected channel" might be
printed to the user.

To avoid that, extts events shall be disabled when PTP is released.

- `Linux >= 172db5f91d5f7b91670c68a7547798b0b5374158 < 9f69b31ae9e25dec27ad31fbc64dd99af16ee3d3`
- `Linux >= 172db5f91d5f7b91670c68a7547798b0b5374158 < 00d3b4f54582d4e4a02cda5886bb336eeab268cc`
