Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ice: Don&#39;t process extts if PTP is disabled<br />
<br />
The ice_ptp_extts_event() function can race with ice_ptp_release() and<br />
result in a NULL pointer dereference which leads to a kernel panic.<br />
<br />
Panic occurs because the ice_ptp_extts_event() function calls<br />
ptp_clock_event() with a NULL pointer. The ice driver has already<br />
released the PTP clock by the time the interrupt for the next external<br />
timestamp event occurs.<br />
<br />
To fix this, modify the ice_ptp_extts_event() function to check the<br />
PTP state and bail early if PTP is not ready.
