What it is

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.
