What to do

AI-suggested

Until a fix is applied, avoid triggering the icss_iep_exit() path that disables perout and pps signals or apply any vendor recommended workarounds if available.

Description

A vulnerability in the Linux kernel's ICSS IEP driver could cause a NULL pointer dereference when disabling perout and pps signals during driver exit. This occurs because the driver references a ptp_perout_request structure that may be NULL. The issue is addressed by modifying the function to clear hardware registers directly without referencing the potentially NULL structure.
