CVE-2024-42107 ice: Don't process extts if PTP is disabled

What is CVE-2024-42107?

CVE-2024-42107 is a medium-severity vulnerability in Linux kernel, published on 30 Jul 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

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

ice: Don't process extts if PTP is disabled

The ice_ptp_extts_event() function can race with ice_ptp_release() and result in a NULL pointer dereference which leads to a kernel panic.

Panic occurs because the ice_ptp_extts_event() function calls ptp_clock_event() with a NULL pointer. The ice driver has already released the PTP clock by the time the interrupt for the next external timestamp event occurs.

To fix this, modify the ice_ptp_extts_event() function to check the PTP state and bail early if PTP is not ready.

Weakness: CWE-476, CWE-367
